All three were certainly getting along on Monday night when they attended the Alliance for Children's Rights dinner together in Beverly Hills.

"The family are longtime supporters of the Alliance for close to five years now," an inside source exclusively told E! News, revealing that Mandy and Brian's production company, LH7 Management, sponsored the dinner.

Our source also added that "Mandy was adopted and was also a teen mom, so she relates to our work," and noted that "Mandy will sometimes speak at the events. She talks about raising Selena, about rising above your situation to achieve the most out of life. She's really empowering."

Jimmy Kimmel was not only among some of the other celebs on hand, but he "did a bit of standup" as well.
