'The Fosters' finale ends with lesbian wedding

Monday's summer finale of the ABC Family drama The Fosters ends with a lesbian wedding.

In the show, Sherri Saum (Rescue Me) and Teri Polo (Meet the Parents) play domestic partners living in San Diego, California. The couple is coping with raising three children when a wayward teenage girl – a foster child – is added to the family.

A Supreme Court ruling handed down in June paved the way for California to become the 13th state to legalize gay nuptials.

The couple can be seen exchanging vows in a trailer released by ABC Family.

"You are a piece of work," Lena (played by Saum) tells Stef (Polo), "but you're my piece of work." 

The Fosters will return with new episodes in January.
