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."
Meester, who is returning for season 5 of Gossip Girl
in September, is always crooning for the longhaired Dachshund – maybe a little too much.
"I'm sure my dog has heard every stage of every song that I've ever done from the beginning," she says. "I'm sure she's sick of it."
Trudy (who Meester affectionately kisses "all the time") even has a few nicknames inspired by famous voices.
"She's Trudy Garland, Judge Trudy, Truiah Carey, any kind of name you can imagine," she says.
