Jason Biggs & Jenny Mollen Are Expecting Baby No. 2!

And baby makes four! Actors Jason Biggs and Jenny Mollen are expecting their second baby, and they decided to announce the impending addition in the best way ever. On Wednesday, Mollen posted a hilarious Instagram photo of the couple using a NoseFrida and captioned it: "This is how I told my son babies are made. #numbertwo."

In case you haven't had the pleasant experience of using a NoseFrida yourself, it's a nasal aspirator that FridaBaby advertises as a "natural, hygienic baby booger buster." Who knew it also made for a great pregnancy announcement prop?

Biggs and Mollen are already parents to 3-year-old Sid, who was born in 2014 — and Mollen's been having fun and joking about pregnancy and parenthood ever since he was born. On Wednesday, Mollen told Entertainment Tonight that she and Biggs were "thrilled" about their incoming addition to the family.

"Sid understands that there is something in my stomach but he is growing increasingly more and more frustrated that he cannot see its face," Mollen told Entertainment Tonight. "We don't know the gender yet. I'm hoping it's a poodle."

Biggs, on the other hand, said he "would love a little girl." The couple even shared Mollen's due date, telling Entertainment Tonight that the baby was due in early October.

Mollen and Biggs first announced that they were expecting Sid in July 2013, and shortly after, Mollen penned an honest, hilarious, and heartbreaking essay for Cosmopolitan revealing that she had had a miscarriage in 2008, only six months after she and Biggs started dating. And ever since she had Sid (whose birth Mollen shared short clips of on Instagram), Mollen has been just as open and honest in discussing parenthood.

Soon after she gave birth in 2014, Mollen told the Huffington Post, "[Sid]'s 3 and a half months old and I still don’t feel like I really know what I’m doing. As far as he’s concerned, I’m like 'No worries, I’ve got this.' But in reality, I’m sort of holding my breath trying to get it right."

As for Biggs, he told People last year that fatherhood had changed him entirely. "That change that happens is so tangible," he said. "It happens overnight, and it’s the craziest thing."

Hopefully Mollen and Biggs will be willing to continue sharing all of their touching and hilarious parenting insights as they prepare for Baby No. 2. Congratulations to the happy family!
