The couple, who have two children together, got cozy at Complex magazine's 5th Anniversary party on April 10 in L.A. where she told People magazine, "we're pulling out of the separation, we're still married."
On her MySpace page in March, Moakler addressed pregnancy rumors and mentioned her husband.
"i do one day want to have another child with my HUSBAND, but at this time, i am NOT pregnant!" she wrote on March 23.
Moakler and Barker split last August. In a message on her personal Web site dated Aug. 8, 2006, Moakler wrote, "i am very devastated and very much heartbroken over the demise of my marriage and for the upset of my family....I wanted nothing more to overcome the challenges we faced but failed."
In 2005, Barker and Moakler starred in their own MTV reality show called "Meet The Barkers." Moakler was a contestant on ABC's "Dancing With The Stars" last year.
After they split in August, there were reports that Barker hooked up with Paris Hilton. The fling reportedly fueled a spat between Hilton and Moakler at a nightclub in October.
At the time, Hilton's rep said the heiress filed a police report alleging that Moakler punched her, while Moakler's rep said her client had also filed a report alleging that Hilton's ex-boyfriend, Stavros Niachros, pushed her down a flight of stairs.
