Cameron is Diazed and confused after London premiere

Party girl ... Cameron Diaz

CAMERON Diaz looks a little bleary-eyed as she leaves a club after celebrating her latest movie.

The 39-year-old blonde partied to the early hours with co-star Matthew Morrison after the London premiere for What To Expect When You're Expecting. 

After walking the red carpet with Cheryl Cole, who has a cameo in the movie, the pair hit the after party at the Sanderson hotel before moving on Mayfair's Whisky Mist. 

Cameron, dressed in a white, strapless all-in-one trouser suit, his behind her handbag as she left the club - looking little bit worse for wear. 

Glee star Matthew, 33, surfaced at 3am, looking a little dishevelled but still sporting his trademark grin. 

The Hollywood contingent were joined in the club by Royal rugby player Mike Tindall, who left his wife of 10 months, Zara Phillips at home, preparing for her big day today.

Gleeful .... Matthew Morrison at Whisky Mist

She is doing her bit in the Olympic torch procession today - carrying the flame on horseback onto the Cheltenham race course. 

Mike, meanwhile, may well stay in bed.

Night out ... Mike Tindall
