It's certainly not a traditional family, but it sure seems to work.

Yesterday, Bruce Willis and his new wife Emma Hemming joined his ex-wife Demi Moore and her husband Ashton Kutcher at their daughter's high school graduation.

The happy couples watched as 17-year-old Scout received her diploma from the Wildwood School in Culver City, California.

Of course, Twitter-addicts Demi and Ashton tweeted about the event.

"I am so proud she is an amazing young woman and I have learned so much from her already! What a gift!," Demi posted.

While Ashton's posts were filled with his usual sarcasm.

"Gotta pee only 20 diplomas to go," Ashton tweeted before adding, "I can't feel my butt anymore. Thank you hard plastic chair."
