Ashlee Simpson, Pete Wentz and son Bronx, on March 31
Are Ashlee Simpson
and Pete Wentz
reconciling – or just very amicably split
Dressed casually as they soaked up some southern California sunshine – with Wentz carrying 2-year-old Bronx on one hip – the young family stopped by the Beverly Glen Mall in Los Angeles Thursday and picked up some coffee and iced tea at a Starbucks.
"Ashlee and Pete held hands, and Pete especially looked very happy," an onlooker says. "While waiting for their drinks, Pete had his arm around Ashlee and they definitely looked like a couple again."
Added the onlooker: "Ashlee kept smiling and lovingly leaned on Pete."
Though they look friendlier than ever, this isn't their first post-split outing. They've continued to hang out as a family
, even after Simpson filed for divorce in February.
All along, sources have told PEOPLE the couple's breakup is friendly, and that being good parents to son Bronx is their priority.
"They're both focused on making this transition as easy as possible for him," a source told PEOPLE recently.
Added a source close to the couple, "It's very amicable. They're on very friendly terms and speaking – it's fine."
Reps for the two had no comment.
But, despite their upbeat demeanor, another source tells PEOPLE that their outing Thursday doesn't mean the two are reconciling. "This is not a sign that they are getting back together," the source says. "They both care about each other tremendously. They both love Bronx very much, and Ashlee has always called Pete her best friend. They are in the middle of still trying to figure this out."
