Toni Braxton is officially single.
Her rep tells PEOPLE that the Grammy-winner's divorce from her husband of 12 years, Keri Lewis, has been finalized.
"The couple has had an amicable split and will still both be actively involved in raising their two sons, 11-year-old Denim and 10-year-old Diezel
," the rep says in a statement.
Braxton, 45, who married
in 1998, said in her VH1 Behind the Music special
last October that the split
with Lewis in 2009 took a toll on her.
"I had to figure out a plan for my life that had nothing to do with him," she said. "I was angry with everybody. I couldn't believe this was happening to me. I felt that I was a person dealing with a lot of struggles and here comes another one."
The Braxton Family Values
star said in 2010 that she had been diagnosed with lupus and has battled financial problems over the years, filing for bankruptcy twice.
