Jennie Garth and Peter Facinelli are making it work.
The friendly exes proved just how friendly they could be while celebrating Halloween with each other -- and their respective significant others -- at Facinelli's house.
Garth took to Instagram on Monday to share a cute snap of herself and her new husband, actor-producer Dave Abrams, all dressed up for the holiday at Facinelli's Halloween party.
"I'm not sure what we are... maybe a construction site?! fun halloween with my gorgeous husband at my ex-husband's house. #blendedfamily #ilovemyhusband #halloween @deabramsla," she captioned the pic.
Facinelli -- who split with Blindspot star Jaimie Alexander in February -- has moved on with actress Lily Anne Harrison; the two also showed off their couples costumes on Instagram.
"It's Time... #TrickorTreat ☠👻🎃," he wrote alongside a snap of himself and Harrison in their creepy attire.
Garth and Facinelli weren't the only exes who played nice for Halloween.
Half of Hollywood turned up for Kate Hudson's annual Halloween bash -- including her ex, Matt Bellamy, and his girlfriend, Elle Evans.
