Pink and Carey Hart are celebrating their son turning two.

The 39-year-old singer and 43-year-old former motocross competitor spent son Jameson's second birthday together as a family Wednesday.

Pink shared a pair of photos from the fete on Instagram.

One picture shows Jameson smiling down at a new Elmo toy, while the other features the toddler's pink and green birthday cake.

"Two," Pink captioned the post.

"Happy b day to my #2, Jamo!!!! He is such a blast and he'll on wheels!!!!!! These 2 years have gone fast!!!" he wrote.
