(CBS) Tallulah Willis, the youngest daughter of Bruce Willis and Demi Moore, made her official society entrance on Saturday in Paris.
Tallulah attended Le Bal des Débutantes at the Hotel Crillon on Saturday night. She's one of 23 women from 13 countries, all daughters of business leaders, actors and aristocrats, who made their debut on Saturday.
The 17-year-old Tallulah, who donned a black and silver sequined Lanvin dress, was joined by her father and two sisters, Rumer Willis and Scout Willis, for the debutante ball. Rumer tweeted a photo from the event.
"He [Bruce] was a little different than three years ago [when Scout was a debutante], more reserved," an insider told People. "He was there for his daughter, but protective. It wasn't until around midnight when he danced with Tallulah that you saw him become more relaxed."
"He's a dad and he wanted to be certain she felt the evening was for her," the source added about Bruce, who is expecting a baby with his model/designer wife Emma Hemming.
Moore, who recently split from Ashton Kutcher, did not attend the event.
But she did resurface on Twitter for the first time since the break up. "Why do we have only 1 day for giving thanks?," she wrote on Thanksgiving. "Is that why so many people feel unappreciated? Make this 1 of 365 days of Thanksgiving!"
Kutcher, meanwhile, also tweeted on the holiday, writing, "I'm thankful for family, friends, you, & time to reach my potential. What are you thankful for?"
