WATCH: Sara Bareilles helps same-sex couple plan the perfect proposal in new video

This week, singer-songwriter Sara Bareilles released the video for her new song "I Choose You," in which she helps two couples - a different-sex couple and a same-sex couple - plan the perfect proposal and wedding engagement. The song is off of Bareilles' Grammy-nominated album The Beautiful Unrest and is becoming an increasingly popular wedding and engagement song.

One of the couples featured in the video is Aly and Andrea from Denver, CO, who use homemade posters to declare their love for each other and take steps toward elevating their relationship to the next level of commitment through marriage.

Sara Bareilles has been a longtime supporter of gay and lesbian people: Her smash hit "Brave" was inspired by a friend of hers coming out as gay, and she has spoken often about the power of sharing our stories with our friends and family members.

"There's so much honor and integrity and beauty in being able to be who you are," Bareilles has said. "By doing that, you give others permission to do the same. You can choose to love whoever you love."
