Usher's ex 'not stressed over sex tape'

Usher's ex-wife Tameka Foster has revealed that she can't understand why people have such an interest in a rumoured sex tape featuring the pair.

Foster, who split from the singer in June 2009, said that she doesn't know why the footage is considered to be newsworthy.

She wrote on Twitter: "NEWSFLASH!! BREAKING NEWS! GUESS WHAT. I have copulated w/my husband! O_O. Why is this news again?? #ConfusedTweet. End of discussion (sic).

"Yes, I cant stress over what I cant change. Hey I was married, happily. So theres a chance that we might . Its silly 'news' 2 me.

"folks are bored I guess, why do they CARE? Hes my ex- so sex was likely. I dont know abt any tapes, but why do they care??"

Though the footage has not yet been made public, celebrity website TMZ has claimed that it shows Usher and Foster engaging in a series of sexual acts.

It is believed that the recording was among $1 million (£620,130) worth of items that were stolen from Usher's car in December 2009.

A spokesperson for the 32-year-old has not yet commented on the sex tape reports.
