Former Baltimore Ravens linebacker Brendon Ayanbadejo has included his son Amadeus in his gay rights advocacy.

Last year, the 36-year-old Ayanbadejo, who is currently an NFL free agent, vocally supported passage of a gay marriage bill in Maryland and opposed an unsuccessful referendum to repeal the law.

He is currently lending his celebrity to an effort to increase LGBT rights in Florida.

In a photo to support the NOH8 Campaign, which raises awareness and funds for gay rights causes, a shirtless Ayanbadejo holds his son Amadeus. Ayanbadejo has his mouth duct taped and both have the campaign's familiar “NOH8” slogan written on one cheek. A separate photo features the entire Ayanbadejo family.

Other professional athletes who have previously posed for the campaign include former Minnesota Vikings punter Chris Kluwe, former Carolina Panthers linebacker Nic Harris, former NFL defensive lineman Esera Tavai Tuaolo, New York Jets safety Bret Lockett, and Houston Dynamo's Mike Chabala.
