Tameka Foster-Raymond, wife of R&B singer Usher, is once again refuting infidelity rumors, but this time she did it on her Twitter page. The 38-year-old mother of five got into a heated "posting war" with a Twitter follower who questioned why her husband was spotted checking into a hotel with an unidentified woman.

"Your friends have been dropping hints about [you] and Usher all along. Umm, why isn't your husband following you on Twitter?" The blogger asked.

Foster-Raymond, who initially brushed off the comments, eventually responded directly to the heckler. "You're a[n] angry woman. I don't know who hurt [you], but it wasn't me. I will pray for you. I'm happy & life is GOOD for me! Enjoy [yours]."

The "mystery woman" who was spotted in Malibu with Usher, set the rumor mill abuzz with claims of an alleged affair. Speculation grew even more after it was reported that the singer was not wearing his wedding ring. The woman was later identified as an product manager, who was meeting with the Grammy winner for business purposes. This information however did little to convince the blogger.

"So what if that girl is a product manager," she twittered on Foster-Raymond's page. "Weren't you Usher's stylist? And weren't you married at the time?" The blogger went on to say that she was "checking to see if a married man can't creep with his product manager while his wife sits on Twitter."

After going back and forth for several posts, Foster-Raymond deleted the blogger before addressing her one last time. "She is ugly, mad 'cuz she has no man, can't find a good woman, sh--'s all bad!!! I'd be salty nuts too...ya'll sing Kum by Ya for her....lol." Foster-Raymond also stated that she had no plans of addressing future rumors surrounding her marriage.

Since their wedding in 2007, the couple has denied numerous reports of a possible break-up. Not long after announcing his engagement, Usher fired his mother Jonetta Patton as his manager, fueling rumors that his wife and mother don't get along. "I decided to not fire, not get rid of, but to give [my mother] the ultimate compliment -- to retire her to be a full-time grandmother," Usher said in an interview. The pair have two sons, Usher Raymond V, 17 months, and Naviyd Eli Raymond, six months.

The singer's personal life may have affected his professional career as 'Here I Am,' was released to less than stellar sales. Usher has since re-hired his mother and is readying the release of his next album 'Monster.'
