Nice little reunion -- at separate tables! Demi Moore and ex-husband Bruce Willis attended their daughter Rumer Willis' musical performance at hotspot DBA in West Hollywood, Calif., on April 5. However, instead of mingling with each other, the famous exes decided to sit in different areas while supporting their eldest child.

"They stayed after to congratulate her and chat for a bit," an eyewitness tells Us Weekly. "Bruce and Demi did not interact with each other."

Moore, 50, was accompanied by one male and two female friends for the special outing, while Willis, 59, was joined by his very pregnant wife Emma Heming-Willis.

Rumer, 25, plays multiple roles in "For the Record: Tarantino," a musical mash-up that pays homage to several of director Quentin Tarantino's blockbuster hits. One of the roles includes "Pulp Fiction" character Mia, which dad Bruce starred in back in 1994.

"Bruce was cheering Rumer on. So was Demi!" the eyewitness told Us.

The "Margin Call" actress and Willis split in 2000 after 13 years of marriage, and are also parents to daughters Scout, 22, and Tallulah, 20. Moore, who has been dating rocker Sean Friday for nine months, attended Rumer's cabaret show last month. The star had a "joyful" demeanor during the performance, which came on the heels of news that ex-husband Ashton Kutcher is expecting his first child with fiancee Mila Kunis.

As for Willis, he's expecting baby No. 2 with Heming-Willis, 35, any day now. The pair returned from a babymoon at their vacation home in Parrot Cay, Turks and Caicos, back in February; their baby-to-be will join their daughter Mabel, 23 months.
