British actress/model Kelly Brook has sparked speculation she is a married woman after mentioning her "husband" in a cryptic online post.

The Piranha 3D star dropped a number of hints about her relationship status in a series of cryptic messages posted on on Friday (30May14).

In the messages, which were posted while Brook was onboard a Eurostar train between London and Europe, she called her partner David MCIntosh her "husband" and mentioned "wedding celebrations".

She wrote, "Look how happy my husband looks... #Eurostar #France #WeddingCelebrations."

Brook tagged two friends, who are due to marry on Saturday (31May14), in the post, suggesting she and MCIntosh are on their way to celebrate their pals' nuptials, but she did not explain why she called her fiance "husband".

The pictures she posted show the couple smiling and hugging on the train, and enjoying a lunch of pastries, chocolate, beer and cheese.

The couple became engaged in March (14) after a whirlwind romance.
