Toni Braxton can't wait to get married again.

The 'He Wasn't Man Enough' hitmaker split from her musician husband, Keri Lewis, in 2009 and divorced him last July after 12 years of marriage, but is still a romantic at heart.

She said: ''I was disappointed in love. I'd think, 'Oh God, I'm singing 'Unbreak My Heart,' and it's my life!' But now I'm in a better place. I can't wait to get married again.''

The 47-year-old star has two sons, Denim, 12, and Diezel, 11, and felt very guilty when her youngest child was diagnosed with autism.

She said: ''I thought I was being punished for having had an abortion. But I realised there is nothing wrong with my baby. He just learns differently.''

Although she is in a very happy place now, the six-time Grammy Award-winning singer - who reflects about her roller-coaster life in her new memoir 'Unbreak My Heart' - also initially struggled when she decided to part ways with her family group The Braxtons to go solo and wasn't sure whether to include details of their split in her book.

She told People magazine: ''Writing about it was therapeutic, but then I felt guilty because I had to tell a little of others' stories to tell mine.''
