Planning a wedding is no easy feat — especially when you’re also pregnant, moving to a different state, raising a 4-year-old and in the thick of custody issues with said 4-year-old’s father. However, instead of becoming a bridezilla — which would have been totally understandable — Kailyn stepped up to the plate like a true rock star, balancing all the details and drama with patience and grace.

Throughout Season 5 of “Teen Mom 2,” we’ve watched Kail organize every inch of her aquatic-themed nuptials, and it’s all led up to this: the big day! In the sneak peek of Tuesday’s episode below, viewers get a front row seat at the ceremony, as well as an intimate peek at a tender moment leading up to Kailyn’s trip down the aisle.

First, in a room filled with friends and family, the handsome groom takes his spot next to the wedding officiant, and he’s already on the verge of happy tears. “I’m gonna start crying already,” Javi says to his best man.

Backstage, Kailyn looks absolutely gorge in her lacy, mermaid gown, and takes deep breaths to keep her own waterworks at bay. However, when son Isaac, donning a dapper gray tux and lavender bow tie like the rest of Javi’s groomsmen, approaches his mom, she can’t stop the feels from comin’.

“What happened to your eyes,” Isaac sweetly asks.

“You’re making me so happy,” Kailyn responds, smiling from ear to ear.

If this clip is any indication of what the entire episode has in store, y’all better have a box of tissues handy before it starts. Tune in Tuesday at 10/9c to bear witness to Kail and Javi’s dream wedding.
