*Usher’s ex-wife Tameka Foster can’t understand why people are interested in the fact that a sex tape  of the pair – who split in June 2009 after two years of marriage – is being shopped  for sale, as they were only doing what married couple do.

She tweeted: “NEWSFLASH!! BREAKING NEWS! GUESS WHAT. I have copulated w/my husband! O_O. Why is this news again?? #ConfusedTweet. End of discussion.”

“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?? (sic)”

Though the footage has not yet been made public, TMZ confirmed it is Usher and Tameka engaging in a number of X-rated acts.

It is believed the recording was among $1 million worth of items that were stolen from Usher’s car in December 2009.

A rep for the 32-year-old singer – who has sons Usher V, three, and two-year-old Naviyd Eli together with Tameka – has yet to comment on the sex tape reports.
