Coleen Rooney is pregnant.

The 26-year-old star has announced she and Manchester United player Wayne Rooney are expecting their second child together.

Coleen - who already has two-year-old son Kai with Wayne - is still in her first trimester and will give birth in May.

She tweeted: ''A few people guessed, so news is out ha!! Me wayne and Kai are thrilled that we are expecting a new addition to our family around May time x.

''It's still only early but bursting with excitement! Also wanted the news to come from us, before anyone else! (sic)''

Coleen has previously admitted she would love to have a large family.

She has said: ''I'd like to have maybe three or four children. I'd be happy to be a full-time mum.''

Coleen - who Wayne wed in Italy in 2008 after a five-year engagement - gave birth to Kai in November 2009 with her spouse by her side.

A source said at the time: ''Wayne was a star with Coleen. He didn't leave her side from the moment she came into the hospital.

''When Col gave birth, Wayne's eyes welled up. As soon as he was handed the baby, the tears began.''
