Why did Kelly Osbourne keep her relationship under wraps?

London: Singer Kelly Osbourne says she deliberately kept her relationship with Matthew Mosshart a secret.

The ‘Fashion Police’ star has been dating Mosshart for a year but only recently made her romance public. Osbourne says she did so in order to get to know him properly without being scrutinised.

"I wanted to give it time, I wanted to get to know my boyfriend before the world does. You can`t keep something a secret forever," a website has quoted Osbourne as saying.
