Ryan Reynolds jokes that he has a new form of 'birth control' with wife Blake Lively

Ryan Reynolds and wife Blake Lively are trolling each other on social media once again.

The 32-year-old former Gossip Girl star posted a photo of her 43-year-old husband to her Instagram Stories, writing: "I dare you to forget this every time you see him for the rest of eternity."

The photo showed Reynolds rocking a tiny ponytail with a blue hair tie.

Reynolds replied by re-posting her story, trolling not just Lively, but their kids too.

"Clearly your birth control doesn't work so…" he wrote, alluding that his new look could be effective instead.

Reynolds and Lively share three daughters: James, five, Inez, three, and a third daughter whose name has not yet been announced. The actress gave birth in September 2019.

At the beginning of the month, Reynolds opened up about how he's managing quarantine with Lively and their girls — revealing he doesn't "miss masculine company at all."

"Really, most men tend to just be the architects of someone's demise. So it's fine. I like just being here with the girls. I like doing the girls' stuff," he said on The Late Show With Stephen Colbert.

"I try not to push sort of gender normative ideas on my kids as they're born, but each one as soon as they came out of the chute, they wanted to make dresses, they wanted to dress in hot pink all day. That's what I've been doing."
