MTV's Jenelle Evans basked in some quality family time on Monday as the Teen Mom 2 star celebrated a very special occasion.

Jenelle Evans Claims Son Kaiser Is Not Living With His Grandparents 

Evans announced precisely why she was so excited on Twitter that morning, posting a heart beside her enthusiastic declaration.

Jenelle Evans Reveals What 'Matters Most' On 'Teen Mom 2' 

Born June 29, Kaiser is the second child for both of his parents, though their first together. Evans already has 5-year-old Jace, who lives with her mother Barbara. Kaiser's father Nathan Griffith also has a daughter from a previous relationship. While Evans and Griffith aren't married, the two live together in North Carolina with little Kaiser. Jace, who's been visiting his mother more and more this past summer, was present at Evans' house for the littler celebration.

In case there were any who doubted Evans claim of a busy household, the mother of two shared a picture on Twitter of Griffith and Jace curled up on the couch.

Over the last few weeks there's been talk of a potential custody battle between Evans and Barbara, especially now that Evans is back in school and has been doing well for a while now.

No legal action has been set in motion at this time, though it could happen soon. Evans maintains that it is a sensitive issue and that she would like to continue having a good relationship with her mother, who has grown accustomed to having Jace in her care over the last five years.

Teen Mom 2 continues on MTV with its fifth season Wednesdays at 10 p.m. ET/PT.
