Tyler Baltierra Turns 21 Today! What Are His Birthday Plans With Catelynn Lowell?

It seems like just yesterday that we met Catelynn Lowell and Tyler Baltierra on the first season of 16 and Pregnant, but it’s been almost five years since the young parents gave up their daughter, Carly, for adoption.

The now-engaged golden couple has been going strong — in fact, they’ve even hinted at eloping — and as Tyler turns the big 2-1 today, January 12, they’re obviously celebrating together!

And though they haven’t revealed their detailed plans yet, Cate tweeted about staying sober during the festivities.

“Tomorrow is @TylerBaltierras 21st birthday!!!!! Looks like I'm going to be his DD. Everyone have a safe weekend,” she wrote yesterday.

However, it looks like Tyler will be having some fun — even if his lady love will just be guzzling seltzer.

“21...tomorrow... #Lehgo #CHYeah,” he tweeted. Whoa. Looks like we have Ryan Lochte 2.0 on our hands!

What do you think Cate and Ty will do for his birthday? Leave your b-day comments and suggestions for them below!
