Singer Katherine Jenkins has taken to Twitter to deny rumors that she and married soccer star David Beckham had an affair.

In a series of tweets on Aug. 24, Jenkins, the Welsh beauty who became a favorite when she appeared on season 14 of "Dancing With the Stars," said: "Dear Twitter friends, I've read some horrible rumours on here & want u 2 know I absolutely deny I've had an affair with David Beckham.

"The rumours are very hurtful, untrue & my lawyers tell me actionable. I've only met David twice: once at the Military Awards in 2010 & on a night out in the West End in Feb 2012. We were out in a group of friends & it was just a normal fun evening out. Just so we are clear I have never been on my own with him and never arranged to meet up," she wrote.

Beckham and his wife, Victoria, have four children together. The L.A. Galaxy player has also denied the rumor.

"Unfortunately, we have to deal with this type of nonsense on Twitter. One minute David is dead, then the more scurrilous rumors, there is no truth to any of it," a spokesman for Beckham said, according to E! News.

Jenkins has reportedly received death threats over the alleged affair. One Twitter user wrote that he would "cut" the classical singer if the Beckhams split up, The Sun reported.

Jenkins reportedly has informed police of the threats, and they appear to be taking the matter seriously, but some people are questioning why the singer would take to Twitter to so publicly refute a rumor that very few people knew about.

Apparently poking fun at Jenkins, singer Lily Allen issued a pair of tweets saying: "I'm really upset at the hurtful rumours going round about me having an affair with Jay Z. My lawyers tell me they are actionable. I've met him twice, once at the spotted pig in New York and once at the wireless festival. We have never been alone together etc etc."
