Matthew Morrison on 'Summer Rain': 'It Was About an Ex'

"Glee's" charming teacher Matthew Morrison spoke to "Extra" about his new single, "Summer Rain," and how he came up with the lyrics.

"It was about an ex-girlfriend of mine in New York. She was a Broadway dancer and we had a great two-year relationship and she was awesome. She's married now, she has a kid, but she loves the song and is very happy I wrote it."

The singer admitted he contacted his ex and asked for her approval. "I actually sent it to her before it was released and everything. '[I asked] is this alright?' And she's like 'yeah.'"
