The proud mama took to Instagram on Tuesday to share a series of sweet snapshots to celebrate Ace's 2nd birthday.
"Happy Birthday Ace #2," she captioned a cute family pic with her son and hubby Eric Johnson.
A second photo showed the tiny tot, who was rocking a blue printed button down and graphic shorts, hamming it up for the camera as he posed for a picture on an inflatable slide.
"2yrs OLD?!?! Can we live here forever?" she wrote. "I love you Ace Knute Johnson. Happy Birthday!"
The blonde bombshell also posted a pic of the little man in her life as his birthday drew to a close, including one hilarious photo of him strapped into his car seat on the way home from dinner, rocking what she called a "Harry Styles"-esque 'do!
We can't get enough of this adorable family-- don't forget about Jess' mini-me, Maxwell!
