An excited Jessica celebrated her birthday with friends at Faces nightclub last night (Saturday, 22 September) and even treated club goers to a rendition of 'Dance All Night', which will enter the official chart later today.
The birthday girl tweeted: "Having the best time @faceshoddesdon1 ! Giant bday balloons, cake and champagne! About to perform.... #DanceAllNight."
'Dance All Night' entered the Official Midweek Chart at number 27 and Jess will find out today its final chart position.
Jess's boyfriend and TOWIE co-star Ricky Rayment didn't join her on her girly night out. He'd earlier tweeted that he'd been feeling ill after the couple returned from their sunshine break to Egypt.
Last night's fun marked her second major birthday celebrations, after having a night out on Friday (21 September) at Sugar Hut with several TOWIE cast-members including Bobby Norris and Mick Norcross.
And aspiring pop star Jess isn't the only TOWIE star celebrating a birthday this week.
Cara Kilbey marked her own birthday on Saturday night (22 September) with a big night out in London attended by co-stars including Lucy Mecklenburgh, Frankie Essex and Lydia Bright, who is dating Cara's brother Tom Kilbey.
The group enjoyed dinner at Gilgamesh followed by a party at Cafe de Paris, although pal Lauren Goodger was a no-show after celebrating her own birthday the night before.
She tweeted: "Gutted I'm missing my girls bday night @carakilbey I'm bed bound with hangover! Enjoy have one for me! Love ya x x."
Lauren, who announced she was taking a break from the show at the end of the sixth series, enjoyed a night out for her birthday on Friday (21 September), where she partied with a whole host of TOWIE stars, including Frankie, Lydia, Cara and Billi Mucklow.
The 26-year-old, who was dressed in a flowing purple gown, turned up to her own party after 11pm, which prompted Cara to tweet: "Oh finally the diva @LaurenGoodger decides to turn up to her own party at 11. Thought she got the wrong venue."
Lauren later tweeted: "Want say Big Thank u for my cards n presents and my family and friends for making my birthday so special I'm so lucky have u! Love u lots x"
The Only Way Is Essex wrapped its sixth season last month with Lauren's tearful announcement that she needed some time away from Essex to focus on herself.
A spokesperson later told Reveal that it was a "mutual decision" between Lauren and the producers for her to not appear in the new series, while a source told us an "open door policy" has been put in place meaning she can return when she wants.
