"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," the Fantasy Factory host captioned the photo of him giving his wife a smooch while holding a sonogram in his hand. The couple donned matching white outfits while white and blue balloons hung in the background and huge silver balloons spelled out "Oh Boy" behind them.
In another photo Bryiana, 24, posted onto her Instagram, Rob holds her growing belly while she smiles down at him.
"I can't help but believe the world really could use more Rob Dyrdek's. 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," she wrote.
