Kimberly Wyatt "thank God" for Skype when it comes to maintaining her long-distance relationship.

The former Pussycat Doll star travels between the UK and her native America as a judge on British TV talent show Got to Dance.

Kimberley has been dating Kevin Schmidt for three years and says the distance between them is difficult at times.

"It's not easy. We've lived a long-distance relationship the entire time three years but thank God for Skype and phones and emails," she told the British edition of OK! magazine.

Kimberly hasn't ruled out marriage.

However, the 29-year-old star has been directly affected by the breakdown of a relationship so is wary of committing too soon.

"I don't know if either one of us believes in marriage. I think about it a lot. Weddings are always something I dreamed about as a kid but I don't know if they stand for the same things they used to," she mused.

"My parents went through divorces so I saw a broken home affects lives. My sister's going through a divorce. It's such a heartache and stressful and sad. I don't want to put myself through that."
