Cheryl wasn't going to celebrate her 30th birthday quietly... so herself and the gang headed out to Las Vegas for a few nights of living it up.

And they certainly did just that, judging by the photos on Twitter this morning.

The snapshots show Cheryl crashed on a couch in the Hakkasan club with her boyfriend Tre Holloway and her Girls Aloud bandmates Nicole Roberts and Kimberley Walsh.

Kimberley and Nicole joined Cheryl for the celebrations. 

According to the Daily Mail, the girls and Tre were seen dancing and drinking vodka and Red Bull combos until 4am.

It was reported that Cheryl splashed out about £50,000 on her birthday celebrations.

A source said, "Cheryl's been through so much in the past few years and she's actually really proud to reach the age of 30.

"She's not one of those girls to mope about her age, instead she sees it as a great chance to celebrate.

"So, along with Tre, she's been planning this party for ages. She wanted to treat those closest to her, that's why she 's paying for their flights and five-star accommodation out there."

Cheryl was also quick to thank her fans, tweeting, "Awwww!!! Thank you all sooo much for my birthday wishes, you are the sweetest!"
