布鲁斯·威利斯和黛米·摩尔(1)

They divorced in 2000, but Bruce Willis, 65, and Demi Moore, 57, have remained close friends over the years- and they're now proving it by self-isolating together alongside their daughters Tallulah, 26, Scout, 28, and Rumer, 31.

On April 6, Tallulah revealed they were all under the same roof when she posted a photo of her parents and sister Scout (along with Tallulah's boyfriend, director Dillon Buss)looking cozy in matching green-and-white striped pajamas.

A Moore source says it's not unusual for the couple, who were married for 13 years, to be spending time together. "Demi and Bruce have been best friends for years. They are very close," says the source,

who adds that Willis helped Moore through some very challenging times, including her 2011 split from Ashton Kutcher, 42. "When Demi was dealing with her divorce from Ashton and substance abuse, Bruce was always around for support.

He is the one who helped Demi have a good relationship with her daughters again." Meanwhile, Willis, who married model Emma Heming, 43, in 2009, has been apart from her and their two young daughters, Mabel, 8, and Evelyn, 5, who have been staying at their L. A. home.

But despite the distance, a friend of the family says "everything is great" between Willis and Heming.
