Solange Knowles had a happy birthday indeed. Beyonce‘s little sis enjoyed her big 2-6 at the Hackney Festival in London, where Jay-Z, Bey and Co. had surprises in store for her.

Beyonce treated Solange to a helicopter ride, which Solange posted photos of on Twitter. So sweet! The ‘Love on Top’ singer seems to have a thing for aviation — she got Hov a plane for Father’s Day!

Bey wasn’t the only one giving Solange b-day love, either. Proud brother-in-law Jay-Z gave Solange a sweet surprise. At midnight following his performance at the Hackney Festival, Jigga, Bey, Kanye West, Rihanna and more pals began to sing ‘Happy Birthday’ to Solange, then presented her with a cake and champagne. A source revealed, ”It was really sweet. Solange hadn’t even noticed that it had turned 12 a.m. when Jay got everybody singing together. She was really touched.” So adorbs! Can we be adopted into this family?

The birthday celebration was a pleasant way to end a somewhat dramatic day. Earlier in the evening, Beyonce was upset when a concertgoer insulted her while she was moshing to Jay-Z and West’s performance. A source said, “Whatever was said, it really upset Beyoncé. Jay-Z’s bodyguards weren’t going to have any of it. They waded in and there was a massive ruckus. It got pretty ugly and Beyoncé was whisked away so she wouldn’t get caught in the middle of it.”

Sounds like Bey rose above it — in more ways than one!
