London: Irish pop star Sinead O'Connor says she is back with her former husband, a week after saying their 16-day marriage was over.

The 45-year-old singer, who married for the fourth time with Barry Herridge in Las Vegas on December 8, said on Boxing Day that they had split up, blaming work pressures behind it, according to reports.

But the singer had a change of heart and posted a series of messages indicating her marriage is back.

"We're gonna return to being boyfriend/girlfriend and be sickeningly happy and go to counselling and move in, in like a year, like regular people," she added.
