They've been dating for six months after meeting on holiday in Dubai at the end of last year.

And it would seem Michelle Keegan and Mark Wright's relationship is going from strength-to-strength after the 26-year-old TV presenter posted a touching Twitter tribute to his gorgeous girlfriend on Saturday night.

The couple had been enjoying a night out on the tiles at Manchester's Great John Street Hotel, where they had been celebrating Michelle's Coronation Street co-star Brooke Vincent's 21st birthday.

But it would seem the loved-up pair slipped away from the action for a few minutes to capture a keepsake from the evening as they put on an extremely amorous display in a photo booth.

Evidently not content with a simple smile or pout, Michelle and Mark seemed to get a little steamy as they cuddled up to each other for a passionate kiss.

Wrapping her arms around her man's neck, the 26-year-old actress enjoyed a particularly heated smooch with the former TOWIE star before planting a smacker on his cheek as he grinned into the camera.

Posting the sequence of pictures on his Twitter page, Mark declared: 'Forever @michkeegan.'

It's little wonder the Take Me Out: The Gossip host looked so smitten with the soap beauty, with Michelle living up to her Sexiest Female title in an elegant flowing grey jumpsuit.
