that selects birthday PIE. 2) What ANIMAL eats their cake (pie) without first blowing out the candles. @vancityreynolds that's who. Happy Birthday. I honestly can't believe we're still married."

That last little quip is...so Blake and Ryan. These two love to poke fun at each other on social media. In September, Reynolds posted on Instagram to celebrate the birthday of their family dog, Bax.

"Happy Birthday, Bax," he wrote. "I'd bake you a cake, but it would kill you. Not because you're a dog. Everything I bake is poison. If I had to go to war, I'd just bring a toaster oven."

Lively responded with a dig of her own: This is almost as sweet as the birthday post you did for me this year." Reynolds did not make a birthday post for Lively's 33rd birthday in August.

But she knows how to dish it out, clearly. On Reynolds's birthday last year, she posted these images from her camera roll: "It's like my iPhone captured everything you need to know about my relationship in 2 simple images...," she wrote.

Lively and Reynolds take the time to have some fun with each other online, but they also have a big handful of responsibilities going on outside of Instagram. They now have three daughters, James, Inez, and Betty. Betty's name was revealed on Taylor Swift's latest album, Folklore, on a song called...Betty.

"We haven't yet!," Reynolds said in December of last year whenToday hosts asked about the baby's name. "We're gonna be original, and all the letters in her name are silent. I want to give her something to push against in life."

Always the joker.
