It’s no secret that Leighton Meester has a set of pipes. But the Monte Carlo star also enjoys songwriting – for her dog!
“I sing everywhere,” Meester tells PEOPLE. “I will sing to my dog … I have a song for her that I sing. And the only lyrics to it is, ‘Trudy, she’s a dog.’ That’s the only lyric. It’s very melodic and she loves it. She knows it’s her song.”
