The 'Call My Name' singer made sure it was one to remember by jetting over to Vegas for the occasion and she was treated to a swanky dinner as she brought in her 29th birthday.
The table was covered in balloons and all of Chezza's guests wore Cheryl Cole masks as they dined at the table with her.
And the birthday girl was given a GIANT birthday cookie instead a cake - that came in a big yellow box (on the right of the pic above).
Cheryl took to Twitter to declare that she'd been given her dream birthday present, posting: "Best birthday gift EVER.. !! Thank you .. I love you sooo much !! #Youknowmesowell !!!!"

We're not sure she's referring to the chocolate biscuit but we're sure she was pretty chuffed with that too.
Later in the evening Nicola Roberts tweeted a picture of her, Cheryl and Nicola drinking cocktails with the caption: "PATRON".
And she posted a photo of Kimberley grinning, tweeting: "Soooooooo cute !!!!"
And The Voice UK star will.i.am made sure it was extra special for the 29-year-old by joining in the celebrations.
Later in the evening he got the crowd at Encore Beach Club in Vegas to sing happy birthday to Cheryl.
Will, who was DJing at the event, posted: "Me and @CherylCole in vegas for her birthday...#thisislove
"I made the crowd sing happy birthday to @CherylCole in vegas last night...#thisislove there was #amillionlights"
