EDITOR'S NOTE: This story has been updated.

Toni Braxton and her husband, Keri Lewis, are reportedly calling it quits.

Essence.com is reporting that the Grammy Award-winning singer and Lewis, formerly of the R&B group Mint Condition, have suddenly separated after eight years of marriage.

The couple has two seven-year-old Denim and six-year-old Diezel.

There was not news on what prompted the split, but there is widespread speculation that a key trigger was an onstage kiss between Braxton, 43, and singer Trey Songz, 25, after their performance of Braxton's new song, "Yesterday," at the recent taping of the Soul Train Awards in Atlanta.

Her husband was present in the audience.

Songz is also featured in the video for "Yesterday."

They were having problems when their son was diagnosed with autism. This has been going on for while. He's the typical man who leaves when going gets tough. Can handle problems.

Well, Toni you go Girl!, no body knows or understand what may be going on inside the home. To some it may look disrespectful but, I'm sure he's not totally innocent. Besides, it is only a kiss,it doesn't necessarily mean it is a relationship behind it. It could have been part of the performance. Cougars Unite!

toni was wrong to kiss trey on stage in front of her husband. her personal actions were wrong because she knew that keri was going to say something about it.but they were probably going to break up before the kiss.

As a man, if I were to see my wife kiss some other man period it would be over. Only a hoe off the street would do what she did. She on stage kissing dude, get off stage and kiss me? Naw partner, you gotta go.

Lilkunta, I'm sure Keri wasn't worried about Tyson. You can smell the bytch on him a mile away, but that little youngster that she was lip-locked with, now he looks like he might TEAR SUMTHUNG UP!!!!!!!!!!
