The former Corrie actress, who turned 23 on Wednesday (Aug 7), wore a sexy black lace dress from Agent Provocateur which showed off more than a hint of side boob in the lacy side panels!
On Saturday night (Aug 10), Helen partied at Manchester's The Living Room, before heading to The Circle Club with her friends and family, including sister Jessica who also wore a revealing LBD.
Actress Brooke Vincent was one of Helen's many friends who celebrated the special occasion with her. But it was the appearance of footballer Scott Sinclair that caused the biggest ripple on the night.
Helen's long-term boyfriend Scott also attended the party, despite Helen recently moving out of their shared pad after a reported split.
One person who wasn't present was Helen's new BFF James 'Arg' Argent, who couldn't make the celebrations as he was back in Essex after filming a pilot for a new show.
Before heading out, Helen had tweeted: "Had enough of my stressy self I'm going to get drunk."
And, if these pictures are anything to go by, it looks like Helen completed her mission to have a good night!
Happy birthday Helen!
