(LOS ANGELES) -- Charlie Sheen and his ex-wife Brooke Mueller took a trip to Mexico together, according to TMZ.
The pair, who has now divorced, looked quite cozy lying next to each other on lounge chairs, but Sheen told TMZ they're just "good friends trying to be great parents."
Sheen said that the trip was a sort of "birthday/you're doing great in rehab" present for his former wife.
Charlie added that they are "working on mending the bridges, replanting scorched earth. The goal is harmony."
