In other news, the National Theatre’s West End transfer of The Curious Incident of the Dog in the Night-Time has extended its run at the Apollo Theatre by 14 weeks, following huge demand for tickets. It now runs from 1 March to 31 August.

After a sell-out run at the Chichester Festival Theatre, Private Lives is coming to the Gielgud Theatre this summer. Starring Toby Stephens and Anna Chancellor as the divorced couple who fall in love again, this classic Noel Coward comedy is directed by Jonathan Kent and runs from 22 June. Anthony Calf and Anna-Louise Plowman reprise their roles as the pair’s newly hitched and soon-to-be-spurned other halves.

Finally, don’t miss all the excitement building around the Olivier Awards. Firstly, theatre fans are being called on to vote for their favourite long-runner. Then there’s the news that Sheridan Smith (one of my favourite actresses) is going to be hosting the event. And not only is the show being broadcast live on BBC Radio 2, there’ll be highlights on ITV following the ceremony AND a live event for theatre fans in Covent Garden on the night. Put 28 April in your diaries now for a lot of theatrical fun.

If you’re looking ahead to theatre production in London for the summer 2013, I’ve got some great news from the Open Air Theatre. Their summer season will contain a production of Harper Lee’s American classic To Kill A Mockingbird alongside the much-loved musical The Sound Of Music. Christopher Sergel’s adaptation of the Pulitzer Prize-winning Mockingbird will play from 16 May to 15 June. And the Von Trapp family will be encouraging you to Climb Every Mountain and consider your Favourite Things from 25 July to 7 September. These are just two of the four shows on offer at the venue next summer.

It’s been an interesting year for West End musicals. 2011 has seen huge success stories like Matilda and Crazy For You transfer to the West End, as well as The Wizard of Oz, Shrek and Ghost The Musical.

How can 2012 top that? Well, if the rumours are true, we could be in for some pretty exciting new musicals for the Olympic year. There are whispers of Bridget Jones’ Diary The Musical (with the ever-brilliant Sheridan Smith as the lead); murmurs of Viva Forever The Musical (Spice Girls songs and Jennifer Saunders writing – what more could you want?!); hints about a musical version of The Bodyguard, complete with Whitney Houston’s songs; and suggestions of a Wind In The Willows musical too…

While I love rumours as much as the next person, my tips for 2012 are all based on facts. These shows are definitely coming, and you should be getting excited about them!

1. Master Class, Vaudeville Theatre, from 21 Jan
Tyne Daly has already wowed Broadway audiences with her performance as Maria Callas in Master Class. Next month, she’s heading to London to do the same. I can’t wait.

2. Singin’ In the Rain, Palace Theatre, from 4 Feb
One of my favourite films of all time, it’ll be great to see Singin’ In The Rain on the London stage in February. Particularly with star dancer Adam Cooper in the lead role, and Scarlett Strallen as Kathy.

3. Sweeney Todd, Adelphi Theatre, from 10 Mar
I’m thrilled that Michael Ball is heading back to the West End. He’s such a fantastic singer, and an all-round musical superstar. Sweeney Todd has already had rave reviews from Chichester; I’m so excited about seeing this show when it comes to London in the spring

4. Top Hat, Aldwych Theatre, from 19 Apr
I was a big fan of Tom Chambers when he was on Strictly Come Dancing, so I can’t wait to see him in Top Hat in the West End. My parents have already seen this show on tour, and promise that we’re in for a real treat when it comes to the Aldwych next year. And there’s another one of those Strallen sisters to look out for! (Summer, this time.)

5. Wah! Wah! Girls, Peacock Theatre, from 24 May
Just while you were thinking that all I was going to recommend for 2012 were revivals and transfers, I give you a sparkling new musical from Sadler’s Wells, Theatre Royal Stratford East and Kneehigh. It’s East London meets Bollywood, and part of the exciting World Stages London collaboration for 2012.

6. Porgy And Bess, London Coliseum, from 11 Jul
Finally for summertime (when else?!), the Cape Town Opera comes to the London Coliseum to mark 75 years since George Gershwin’s death. This vibrant, physical production of Porgy And Bess shifts the action to apartheid-era Soweto, with all the classical-jazz-opera musical combinations as strong as ever. It should be a real spectacle.

What musicals are you looking forward to seeing in 2012? Let us know in the comments below…

I’ve got three Christmassy announcements, the first from the Old Vic, which is reviving Michael Frayn’s hugely successful comedy Noises Off, directed by Lindsay Posner, over the festive period. Second, a new musical version of Swallows and Amazons will be produced by the National Theatre at the Vaudeville for Christmas; with music by Neil Hannon of the Divine Comedy. And children’s favourite, The Gruffalo will be bringing its terrible tusks and terrible claws to the Lyric for morning and afternoon performances from November to January.

The other new shows announced this week are even further ahead. If you’re planning a theatre trip for next year, you can choose between Singin’ In The Rain at the Palace Theatre, starring Adam Cooper and Scarlett Strallen from February (a transfer of the Chichester Festival Theatre hit); or She Stoops To Conquer at the National Theatre starring Sophie Thompson, Steve Pemberton and Katherine Kelly from January.

And reaching even further into the crystal ball of theatrical future, Regent’s Park Open Air Theatre has announced its plans for 2012. It’ll stage A Midsummer Night’s Dream and contemporary musical Ragtime from May to September next year. Book before the end of April 2012, and you’ll get a special ticket price of £20.12 on all performances during the Games themselves (25 July to 12 August).

This week’s casting news:

• Busted star Matt Willis and Phantom regular Gina Beck are to appear as Fiyero and Glinda in Wicked from December
• The Young Vic has released more details about its production of Hamlet this autumn. Adeel Akhtar, star of Four Lions joins musical theatre regular Sally Dexter and Sherlock actress Vinette Robinson in the show
