Cheryl Cole is never one to be outdone, and her plunging neckline last night would suggest no different.
After Britney Spears almost fell out of her dress during a night out, Cheryl was clearly determined not to be upstaged and showed the world an eye-and-a-half full of cleavage.
She wore her form-fitting Hervé Léger bandage dress (and possibly an uplifting bra?) as she headed out with husband Ashley Cole, bandmates Nicola Roberts, Kimberley Walsh and Sarah Harding and her boyfriend Tom Crane.

For their part, Cheryl and Ashley looked very together 10 months on from nearly splitting over his alleged infidelities.
And as far as his rehabilitation is concerned, his night out with the Cheryl's Girls Aloud bandmates seemed the latest sign that the Chelsea defender had finally made his way back into the fold.
The girl group and their beaus went to Nobu (the original one in Park Lane - so they missed the Hollywood circus surrounding George Clooney and Matt Damon around the corner), to eat before heading to The Mayfair Hotel for drinks.
Predictably, Cheryl and Ashley left at the sensible hour of 11.30pm, while Nicola and Kim followed soon after.

But partygirl Sarah - dressed in a white bow-tie number - and Tom stayed on until 2am.
They got rather frisky in the back of their cab as they left, but all eyes were really on the Coles.
Cheryl's career has soared despite her wedding strife but the 25-year-old, who only began wearing her wedding ring again in September, is determined to make her marriage work.

In the Girls Aloud's autobiography, Dreams That Glitter: Cheryl wrote: 'People make mistakes, stuff happens. I believe everyone should be a free spirit.
'Even in my marriage, Ashley's a free spirit. I'm not his keeper. I believe in letting people live their lives and be free, so Ashley can have time with his friends when he wants, he can go out when he wants.'
'I'm not the type of person to ring him and be like: "Where are you, who are you with, what's happening, what time will you be in, why haven't you answered your phone?"
'I've been that person in the past and I don't like it. I won't let anything change me and make me revert to being that type of girl, because it's not me.'
Nadine Coyle, however, apparently sat the night out. The group were celebrating the filming of their one-off TV special, The Girls Aloud Party, which will broadcast on ITV1 on December 13.

The programme also features collaborations with the Kaiser Chiefs and James Morrison and Cilla Black, Paul O'Grady and Julie Goodyear will also make guest appearances.
Sarah says: '2008 has been a great year for us all and what better way to round it off than with a festive special.'
