It's a boy! MTV's "Ridiculousness" host Rob Dyrdek and his wife, Bryiana Noelle Flores, are expecting their first child, they both announced on Instagram.

The posts also indicated that the couple is expecting a boy.

Rob, arguably MTV's biggest star, shared an image of he and Bryiana kissing while he held up the image of a sonogram.

Blue and white balloons fill the snap and silver balloon letters spell out "Oh boy" while the couple both don head-to-toe white.

"I love @bryianadyrdek_ in so many ways and on so many different levels," he said of his wife. "I could never create the words to express how deeply and truly I love her and us.

"When you have a forever love so great the ultimate way to express it is by creating a child together," he continued. "I am so happy to announce my beautiful wife is pregnant with our first child.

"We are so blessed, so happy and look forward to bringing an amazing young boy into this world."

Like Rob, Bryiana took to Instagram to announce the good news, too.

Her photo, while similar to Robs, showed the professional skateboarder touching her stomach while she smiled and cradled her barely-there baby bump.

"I am so insanely in love with @robdyrdek and every single day I think about how lucky I am to get to spend the rest of my life with a man who is so ambitious and driven, constantly wanting to help others and yet so loving, so caring, so genuine, so chivalrous, so respectful, and always wanting what's best for me and us and our unborn baby," the former Playboy model wrote.

"I can't help but believe the world really could use more Rob Dyrdek's," she said in her lengthy post. "So I feel incredibly blessed and actually proud that we get to bring another great man like him into this world. We love you so much, Baby Boy!! And we can't wait to meet you."

Bryiana used several emojis and used the hashtag "Here comes baby Dyrdek."

Rob and Bryiana married last September after getting engaged at Disneyland in April 2015.
