As we said earlier, “Unexpected” star Caelan Morrison turned 21 yesterday.

And his girlfriend, Mckayla Adkins, published a photo of the couple with this caption:

“My best friend/ boyfriend/ father of my children turned 21! Wish him a happy birthday with a lot of love and positivity!”

In contrast, Caelan posted a similar photo on his profile, and wrote:

“21 years. I couldn’t spend this date with a better woman.”
