Celebrities With Gay Siblings: Adam Levine, Anne Hathaway, Chris Evans And More On Their LGBT Family Members (PHOTOS)

Colin Farrell might have a reputation as a hard-partying playboy, but the "In Bruges" star is revealing his compassionate side by joining forces with his gay brother Eamon for an Irish homophobic bullying prevention campaign.

The Farrell brothers are pairing up with 'Stand Up! Don’t Stand for Homophobic Bullying,' launched last week by the Irish LGBT youth organization, BeLonG To. "Whether it be the attacking of gay students, which I witnessed firsthand happening to my own brother, or students who are in the minority as a result of race or religious beliefs or any other such characteristic that separates them from 'the norm,' it is all wrong and has no place in a just and compassionate country such as I know Ireland to be," Colin is quoted as saying in a statement.

Of course, Farrell isn't the only A-list celeb whose relationship with a lesbian, gay, bisexual or transgender (LGBT) sibling has not only proven crucial on a personal level, but has also inspired them to support causes relevant to that community. "Captain America" hunk Chris Evans has spoken at length about his relationship with gay brother Scott, while "The Devil Wears Prada" star Anne Hathaway, Maroon 5 lead singer Adam Levine and pop diva Cyndi Lauper have all been equally vocal about their LGBT family members.

And in some cases, there's more than one in the family: Rosie O'Donnell, who came out in 2002, recently attended the same-sex wedding of brother Daniel, a New York Assemblyman who helped spearhead the campaign to get marriage equality passed in his state.

So is an LGBT sibling the best accessory for Hollywood's A-list? Take a look at other celebrities and their LGBT brothers and sisters below:
