Kara Tointon couldnt hide her delight as she posed with rumoured fiancé Marius Jensen in London on Monday night.
The beaming actress, 35, rested both hands delicately on her stomach in a billowing, loose-fitting gown at the premiere of The Festival in Leicester Square.
Kara is yet to confirm her engagement to dishy chiropractor Marius but her sparkling ruby ring stood out as she kept her left hand protectively poised underneath her stomach.
A representative for Kara Tointon has been contacted by Metro.co.uk for comment.
Kara was there to support future brother-in-law Joe Thomas, who revisits the realm of break-up comedies for a post-graduation film not unlike The Inbetweeners.
Joe is understood to have proposed to Karas little sister Hannah – who was cast alongside him in the cult TV show – last January after seven years together.
Its now believed that both Tointon sisters, former stars of the ITV drama Mr Selfridge, are set to wed after Kara prompted engagement speculation by presenting a new ring on her left hand this March.
Notoriously secretive of her recent romance, Kara is also believed to have been overheard saying: Im not saying anything – I cringe when I read about my love life.
Her four-year relationship with Artem Chigvintsev was thrust into the spotlight when they won Strictly Come Dancing together in 2010, and before that she had spent two years with EastEnders actor Joe Swash.
