Jamie Bell is a little worried about his almost two-year-old son.
The Fantastic Four star, 29, says the little guy is already showing sign of being a possible daredevil.
The boy's favorite word right now is—gulp!—motorcycle.
"I know, kill me, right?" the actor said at Comic-Con, where he was promoting the upcoming superhero movie with his co-stars Michael B. Jordan, Kate Mara and Miles Teller. "He just has this new fascination with it and I don't know where it's come from."
Not that Bell is complaining really. "It's going good," he said of being a dad. "It's just a dream every day to be lucky enough to have kids. It's a labor of love. It really is."
Bell and his then-wife Evan Rachel Wood welcomed their son in July 2013. Sadly, the couple broke up about 10 months later after two years of marriage.
Bell and Wood first met back in 2004 on the set of Green Day's music video "Wake Me Up When September Ends." Eight years later, the twosome tied the knot on Oct. 30, 2012 in a small, discreet ceremony.
On Father's Day last month, Bell tweeted, "Fathers…Good job. Keep it up. The following day, he tweeted, "#FathersDay" along with a link to "If," Rudyard Kipling's poem to his son.
Fantastic Four will be in theaters on Aug. 7.
