Cheryl makes a boob on the red carpet

Sticky slip ... Cheryl's support shows as she poses with Cameron

CHERYL Cole makes a glamour boob on the red carpet as a corner of her stick-on bra peeps out from her dress. 

The Call My Name singer posed in an elegant white Victoria Beckham gown at the premiere of her new movie, What To Expect When You’re Expecting – and cosied up to co-star Cameron Diaz. 

But she was blissfully unaware her hidden support was creeping out under her arm. 

American beauty Cameron complemented Cheryl’s white outfit with a strapless trouser suit and white earrings. 

And she had nothing but praise for the Geordie lass – who makes a cameo as a reality show judge in the movie. 

Cameron even predicted a Hollywood future for the former X Factor panellist. 

She said of Cheryl: “She’s talented, and she’s so lovely and I think of course this is the beginning of many films for her. 

"I’m sure she can do whatever she wants to.

Something About Getting Lairy... Cameron Diaz

“She really did us a huge favour by coming in and letting us sequester her for a couple of days and take her out to an old abandoned warehouse in Atlanta and make her act for us.” 

After the Leicester Square bash, Cameron and screen husband Matthew Morrison hit the after party at the Sanderson Hotel before ending the night at Whisky Mist in Mayfair. 

The 39-year-old blonde looked slightly worse for wear as she left in the early hours – with a soppy smile on her face.

Night of Glee ... Matthew Morrison

Glee star Matthew, 33, was still bright-eyed and grinning when he surfaced at 3am, although his shirt and tie looked like it had been through the wringer. 

Maybe he’d been in a scrum with Royal hubby and rugby player Mike Tindall, who had infiltrated the party for the pregnancy movie. 

He could have been picking up tips for future additions to the family, a year in to his marriage to the Queen's grand-daughter Zara Phillips.

Royal ruck ... Mike Tindall leaves Whisky Mist

His Royal missus stayed away from the boozy night – a good move as she’s carrying the Olympic torch in the procession through the UK today. 

Hope Mike doesn’t get his beer breath near the flame.
