The stunning singer was also joined by her boyfriend Tre Holloway as the group partied hard at Hakkasan night club.
Last week a source revealed, "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 these girls to mope about her age, instead she sees it as a great chance to celebrate.
"So, along with Tre [Holloway] 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."
The source added, "She's got the whole weekend worked out - slap-up meals, cocktails, champagne, shots and lots of dancing. It's a chance for everyone to let their hair down and go a bit wild."
Chezza sent a tweet of thanks to fans who has wished her happy birthday saying, "Awwww!!! Thank you all sooo much for my birthday wishes, you are the sweetest!!!!!!"
N'awww we wish we coulda been there to party with Chezza but it looks like they might have paid for it the next morning.
Happy birthday Cheryl!
