The 90210 just got a little bit bigger thanks to Teddi Mellencamp's newborn girl! 

The Real Housewives of Beverly Hills star gave birth to baby No. 3! Teddi announced the news on her Instagram Story on Tuesday night. Teddi and husband Edwin Arroyave's bundle of joy joins their daughter Slate, son Cruz and his daughter Isabella

On her Instagram Story, Teddi posted a video from the hospital after welcoming baby.

"Are we healthy and good?" Teddi asked her husband. "Healthy and good," Edwin replied.

Edwin also shared on his Instagram Story that Teddi "was a champ in the delivery room," telling his followers that both mom and baby are "as healthy as can be."

Later in the night, Teddi also posted a video of her baby girl's feet, set to the song, "My Girl."

On Wednesday, the Bravo star returned to social media to share a family photo with her fans.

"Guess what, baby girl. You are stuck with us because we are absolutely in love with you," Teddi wrote alongside the group photo, adding the hashtag #aboutlastnight."

The Teddi Tea Pod podcast host added, "Dove Mellencamp Arroyave. 19.5 inches, 6.8 oz, 5:59pm on 2/25/20 #lovedove."

Teddi, 38, first announced her pregnancy last September and has continued keeping fans up to date as she counted down to her due date.

"I'm no fortune teller but the day you're arriving is very soon," she recently captioned a lingerie-clad photo from her maternity shoot. "The day you'll be embarrassed of this pic is also in your future."

The Bravolebrity also looked to her Instagram followers for guidance on picking a name for her daughter. "We're still a divided household but I feel like we're close," she told us while debating between PresleyShay and Dove

And with just weeks left in her pregnancy, Teddi opened up her newly designed nursery exclusively to E! News.

"There is a picture that says, ‘You are loved,' which I think is a mantra I've said to all my kids. Some of my other Housewives friends gave me some good gifts," the Teddi Tea Pod host revealed. "Lisa Rinna gave me a bunny so that's in there. I have a rocking horse from Erika Jayne. I have an amazing new Doona stroller from Kyle Richards so I'm set up."

Congratulations to Teddi and her family!
