Birthday girl Brooke looked stunning in a green silk dress teamed with spiked gold heels as she celebrated the landmark occasion at Manchester's Great John Street Hotel (June 8).
But her former screen sister Helen Flanagan arrived fashionably late - 2.45am! - only to find the party had finished at 2am and the guests had moved on to The Circle Club nearby.
Her tardy arrival was due to being locked out of her house earlier. She had tweeted: "Long story locked out my house for hours just grim is not the word. I'm coming tho @BrookeLVincent. love you xxx"
Michelle Keegan attended the party with boyfriend Mark Wright and the pair arrived at the venue holding hands.
Michelle played it cool in a grey all-in-one which showed off her deep tan, while Mark looked handsome in his trademark shirt and jeans.
Other celebs who turned out for Brooke's special day included Corrie's Kym Lomas - wearing a slimming LBD - and Emmerdale stars Sheree Murphy and Charley Webb who looked fab in black and white.
We're sure there were some sore heads the next morning!
