Harry Styles' birthday party guests were banned from Twitter.
A-listers inside the One Direction star's extravagent 21st birthday celebrations at Lulu's Café in Los Angeles on Saturday (31.01.15) were forbidden from using the micro-blogging website in a bid to keep details of the exclusive bash a secret.
Ex-girlfriends Cara Delevingne, Kendall Jenner and Kimberly Stewart all attended the £200,000 celebration, as well as his current lover, 21-year-old Victoria's Secret model Nadine Leopold, with a source saying Harry's charm has enabled him to stay friendly with his former flames.
A friend of the 'Steal My Girl' singer told the Daily Mirror newspaper: "He's such a charming guy, even his exes want to be around him. It's a credit to his good nature that girls he has dated all wanted to come and help him celebrate."
The birthday boy - who is worth an estimated £15 million - pulled out all of the stops to mark the special occasion, by hiring out the entire venue and treating those who came to sprinkle-covered cupcakes decorated with the letter 'H', as well as several rounds of karaoke and an instant photo-booth.
Other guests included Adele, 26, David Beckham, 39, Chris Martin, 37 and Jennifer Lawrence, 24, but 'Shake It Off' hitmaker Taylor Swift was not in attendance at the party following the pair's bitter break-up in 2013.
