It's Father's Day this weekend, and while out your celebrating your own father, don't forget to honor the real heroes in life, celebrities. But be careful, because it's not always easy to spot a celebrity dad. There are a lot of celebs who might look like dads, but aren't—it takes more than a permanent look of disappointment in your eyes to make a father. Here are 15 celebrities who are seriously putting off dad vibes, but are actually child free (for now.)

1. Jay Leno's cars are his babies.

The cars, the jokes, the denim on denim. You'd totally think Jay Leno was a dad, but he and his longtime love Mavis (they met in the 70s) made the decision to stay kid-free.

2. George Clooney seems like a dad, but this silver fox doesn't have a litter.

“I’ve always known fatherhood wasn’t for me." Clooney said. "Raising kids is a huge commitment and has to be your top priority. For me, that priority is my work."
