Bruce Willis and Demi Moore seem to have come to the last straw in regards to their daughter Tallulah Willis as the former A-list couple gave her one last opportunity to seek help.

"Tallulah was pretty much given an ultimatum," a source told People. "Her parents were about to take away everything from her."

The source also added that the 20-year-old was heavily affected by her parent's divorce in 2000 but things got worse when her mom divorced for a second time, which led to Moore's hospitalization and stint in rehab in 2012.

"When Demi was hospitalized, Tallulah didn't show up to school for days because she was too embarrassed," the classmate says. "She was very open about Demi's issues and would sort of imply, 'Of course I have issues too, look at my mom.'"

Both parents hope her treatment goes well despite their differing opinions on how to approach it.

"If Bruce suspected that Tallulah had any kind of substance abuse problem, he would have demanded for her to get help," the source said. "Demi's take is that Tallulah is still very young and trying to find herself."
