Bruce Willis & Demi Moore Reunite for Daughter’s 30th Birthday

Bruce Willis and Demi Moore spent the day together for the sake of their oldest child.

The exes were seen enjoying each other’s company with their three girls during Rumer Willis‘ 30th birthday celebration on Thursday. The former couple joined Tallulah, Scout, and the birthday girl at The Beverly Hills Hotel for a celebratory lunch before heading back to Demi’s for a pool party.

Sitting across the lunch table from each other, Bruce and Demi joined in the fun with their daughters, singing “Happy Birthday” to Rumer as she blew out the candle on her chocolate cake.

They Willis family has been together quite a bit lately. Just Wednesday. Bruce took the girls out to dinner, sans Demi, for a father/daughter date.

Bruce and Demi have been tight ever since their marriage ended nearly 20 years ago. The actress even surprised her ex during Comedy Central’s “Roast of Bruce Willis” and threw in some nice jabs only an ex-wife would know.
