Too cute for words!
The former reality star posted the snapshot of her kissing his cheek on Instagram with the caption, "Happy birthday to my little man. He is the light of my life."
Cue the awwws!
Baby Camden appears unfazed by his proud mama's smooch and is seen staring off into the distance.
But what's the one thing we can't stop fawning over? His huge blue eyes match his little blue sweater!
And now that her firstborn is getting older, Kristin's got more babies on the brain.
She told E! News last month that she was ready for "baby No. 2," adding, "I don't have any announcement today, that's for sure, but we're gettin' there."
She and hubby Jay Cutler seem to be enjoying their life as newlyweds, but the blond beauty admitted that things don't feel any different from before they tied the knot.
"Married life is great," she gushed. "To be honest, it feels the exact same...Once you live together and have a baby together, not a whole lot changes. But it's been great and we're really enjoying it. I have an additional ring on my finger, yes."
Maybe it'll be a family of four in the near future!
