Currently in Las Vegas as she celebrates her final year in her twenties, Cheryl Cole was spotted as she enjoyed a meal in celebration of her coming of age.

Some of the members of Girls Aloud jetted off to Sin City to help her celebrate her 29th birthday in style.

And as Cheryl is a girl who by now has it all, one of her dinner guests treated her to a giant birthday cookie which by the looks of it was just what she wanted.
