After pointing into the crowd and telling ET's Nancy O'Dell that his pops was "trying to be inconspicuous," the 41-year-old actor admitted that his father is very relaxed about the idea of award shows.
"He just wants us to have a good time," Leo told ET.
"I'm happy to bring my dad," he added. "I don't think he ever gets to go on stuff like this, so it's gonna be a fun night for us."
The date seemed like an excellent choice, as Leo apparently started 2016 off a single man -- he reportedly broke up with his girlfriend, model Kelly Rohrbach, a few months ago.
But there was a different nominee on Leo's mind -- Kate Winslet. "She's my favorite actress in the industry," he told ET of his Titanic co-star, who ended up winning the first statue of the night, the Best Supporting Actress award for her role in the film, Steve Jobs.
Winslet returned the kind words when she walked the red carpet, adding that she hopes Leo scores his third Globe tonight.
"I'm very excited for him. It could be him," she told ET of her longtime friend. "He's very cool. He's a pro. We've been through a lot together -- we've grown up."
But the real question is, will Leo finally score an Oscar thanks to this dramatic role? Maybe his dad will prove to be his good luck charm this awards season!
