The singer — who took a break from music after being dropped by her former record label, having her first child with and divorcing rapper Nas — is reemerging with a new sound, new look, and a new place to call her label home.

She leaked the new single today via her twitter page and followed it up with a message to fans, saying she’s wrote it with “love and life in mind.”

Kelis compares her life to a song being sung in acapella and once love enters it, it’s brimming with pulsating beats and synthesis as illustrated by production by David Guetta. Although the overall sound is nothing new, the sincerity in the lyrics mixed with the danceable beat makes it pretty refreshing.

Kelis’ as-yet-untitled album is, she says, “pretty much done” and will be released in 2010.

However, different story go for her lifestyle. There is some rumors have swirled for nearly a year over the current status of the marriage between one of hip hop’s royal couples, Nas and Kelis.

Reports began surfacing that the couple had broken up after a blind item about an R&B singer being caught in a sex tape with someone other than her rapper husband appeared on several gossip blogs. The gossip seemed to quiet down a bit when Nas announced his wife was pregnant with their first child together in February, but the lack of public appearances together did nothing to keep the rumors at bay.

Vibe magazine confirmed today that Nas and Kelis are no more. According to the papers obtained by the publication, Nas and Kelis have been officially separated since April 20 with Kelis filing for divorce today (April 30).

“I can confirm that she has filed for divorce,” a spokesperson told Vibe. “We request the media to respect her privacy during this very difficult time.”

The pair had been married for over five years; they tied the knot in July of 2003 in an intimate ceremony in Atlanta.

Their unborn child, a boy, is due July 21.
