Kelly Brook has sparked a storm of speculation that she and fiancé David McIntosh may have secretly married with an unexpected tweet today. The 34 year-old British model and actress seemed to taunt her Twitter followers by referring to the former royal marine as her "husband."

Tweeting a snap from the couple's travels to France on the Eurostar, Kelly wrote "Look how happy my husband looks :) #Eurostar#France #WeddingCelebrations @grifco @laurentoub (sic)"

The "#WeddingCelebration" hashtag actually refers to a pal's wedding and the reason for Kelly and David's French excursion. However, Kelly's labelling of her lover as her husband has prompted gossip that the couple have managed to wed outside the spotlight.

Having dated since a 2012 New Year's Eve party, the pair got engaged last month and Kelly announced the exciting news herself via Instagram. She posted a photo of herself and David looking happy whilst holding an "Engaged" balloon. "Lovely weekend in Wigan meeting my new extended Family.Such happy times and excited to share my life with the most wonderful man I've ever met" she captioned the snap.

David reportedly proposed after just 12 months of dating, minus a short split in February but sources have said that the underwear model probably bought her own ring. A source said: "David proposed without a ring and friends think Kelly probably shelled out for her own," via The Daily Mail.

"He's hardly the most romantic man in the world and she's got far more cash than him," the insider continued, adding "They rushed into the engagement and then realised they needed a ring to prove it's for real when they got photographed together. Her friends are privately saying they don't think the romance will last."

Neither Kelly Brook nor David McIntosh have publically confirmed the reports.
