This isn't the first time the exes have reunited. Arnett attended the Parks and Recreation actress' 41st birthday party just two weeks after Us Weekly broke news of their separation.

A source told Us their split was "very amicable" and they "have a lot of respect for each other."

"There's still love between them," the insider explained.
