Tyler Joseph is embarking on a new "Ride" — fatherhood!

The Twenty One Pilots frontman, 31, and his wife Jenna are the proud parents of a baby girl, Jenna shared on Instagram on Friday.

“meet Ro,” the new mom captioned a video of the new family of three, using a nickname for their baby girl and revealing her full name and date of birth. “fresh out of the oven. Rosie Robert Joseph was born February 9th. Robert after Tylers middle name.”

In another Instagram post, Jenna wrote, “our daughter, Rosie.”

“Ro and I are finding all the sunspots in our house,” she added.

“She was born on Sunday so we celebrated her 1 week Sunday with sun and cinnamon rolls and sunday service on tv.”

Jenna, 26, also posted a sweet tribute to her “supportive” husband on Friday, saying that she’s “lucky” to have him in her life.

“you’re a thinker, you’re a trooper, you’re a fixer, you’re a looker still at 6am with no sleep. you work so hard. you are the most diligent and supportive person, I’m lucky you’re my person. Rosie and I love you.”

The new parents seemed to be infatuated with their new bundle of joy, as Jenna also shared a video on her Instagram Stories of Tyler recording a video of the family through a mirror, and later, a shot of the musician holding his daughter at the doctor’s office.

Choosing an extra special way to share the couple’s pregnancy news with fans, Joseph made the announcement during Twenty One Pilots’ Lollapalooza Berlin set in September.

During the set, the musician was joined onstage by his wife, whom he married back in March 2015 after getting engaged in Paris the previous year. For their big baby reveal, Jenna wore a patterned dress that showed off her growing bump.

“I know I said I’m bringing a couple people onstage, and that’s true,” Joseph said, dropping to his knees to kiss his wife’s stomach as the crowd erupted into screams.

With big smiles on their faces, the then-parents-to-be went on to share a sweet kiss on the lips before walking together offstage.

In the months following their announcement, Joseph and Jenna shared little glimpses into their life as they got ready to welcome a new member into their household.

“Soundcheck,” the "Stressed Out" singer wrote in late December, captioning a pair of snapshots showing his wife sitting on the floor of what would be the baby’s nursery, cradling her bump as boxes were scattered about.

Two days after Joseph let the cat out of the bag, Jenna shared a collection of images of her smiling husband cuddling up close to her baby bump while they enjoyed a dip in the pool.

“We are pregnant! We’re having a girl!” she wrote in her post, joking in addition, “Tyler already likes to take pictures with her more than me.”
