Demi Moore skips daughter Tallulah's debutante debut
But although dad and sisters Scout and Rumer (who tweeted a pic, above) were all on hand, Moore was conspicuously absent.
"He's a dad and he wanted to be certain she felt the evening was for her," a source tells People magazine of Willis' attendance.
Moore, for her part, did resurface on Twitter on Thanksgiving, to send out this message: "Why do we have only 1 day for giving thanks? Is that why so many people feel unappreciated? Make this 1 of 365 days of Thanksgiving!"
