Peta Murgatroyd is "officially obsessed!"
The Dancing With the Stars pro took to Instagram on Wednesday to share an adorable new pic of son Shai to celebrate his 3-month birthday.
"I'm officially obsessed #3monthsold #babychmerkovskiy ???," Murgatroyd wrote alongside the cute snap.

Shai's dad, Maksim Chmerkovskiy, also took to Instagram to celebrate the big day, commemorating the occasion with a sweet photo of Shai with his grandpa.
"Birthday Boys! 57 years young OG and 3 months old YG! ?????#GrandpaSwag #babyChmerkovskiy," he captioned the shot.

While baby Shai gets a 10 for cuteness, Murgatroyd and her partner, Nick Viall, have started to struggle on Dancing With the Stars.
"I'm always looking to get better," Viall told ET after he and Murgatroyd narrowly escaped elimination last week. "So, regardless of what the judges say, as long as I'm still here, I'm going to try to get better and hopefully I will and still enjoy this experience."
