This Video Of Tyler Baltierra & Daughter Nova Will Melt Your Heart!

Cutest father-daughter duo...ever!

In a bonus clip for Teen Mom OG, it's a Father's Day celebration! Catelynn Lowell had her daughter, Nova, give her dad, Tyler Baltierra, the gift that she made for him. "That's so sweet," a thrilled Tyler told his 2-year-old daughter.

He told her, 'It's so pretty...so just like you are," as a loving Cate looked on at the duo.

Recently, the MTV dad has really stepped up when it comes to caring for their daughter as Cate seeks help in a rehab center after experiencing suicidal thoughts.

Teen Mom OG airs Monday nights at 9pm ET, only on MTV!
