ViVi Turns One! Kailyn Lowry's Ex Jo Rivera Celebrates Daughter's First Birthday — See The ADORABLE Photos!

Vivi's big birthday! Jo Rivera and Vee Torres celebrated their daughter's first birthday this weekend and Kailyn Lowry shared the most adorable photos from the party!

The Teen Mom 2 star shared this adorable photo of the boys, 7-year-old Isaac, her son with Jo, and 2-year-old Lincoln, her son with ex-husband Javi Marroquin.

Isaac might be the best big brother, ever!

Sibling love!

Over the years, Jo and Kail haven't been on the best terms over custody and child support, but these days the two have finally come to terms.

Happy 1st Birthday ViVi!
