London: Hollywood heartthrob Robert Pattinson likes being in love but prefers not to talk about it in order to maintain the ‘mystique’.

The ‘Twilight’ star, who is dating Kristen Stewart is happiest when he is in a relationship but prefers not to talk about it, reported a website.

"I guess I am romantic when I like someone, I like being in love with people and yes, I guess I am quite sensitive to things," he said.

"It's important to preserve any mystique you have and also I just don't feel it's anyone else's business to discuss my personal life," he added.
