Jenelle Evans and David Eason are getting serious.

Over the weekend, the Teen Mom 2 star and her boyfriend of about six months traveled to the zoo, where Eason was seen with his daughter, Maryssa, and Evans' two children, 6-year-old Jace and 1-year-old Kaiser

"The lions were very active today," Evans wrote on Instagram, along with a photo of her boyfriend holding Kaiser as Jace stood at his side.

During a recent interview, Evans offered fans an update on her situation with Kaiser's father, Nathan Griffith.

"It's just a lot of butting heads right now," Evans told PEOPLE Magazine in March. "I think he's really not putting all personal issues aside – he's not making it just about Kaiser. I think he's really jealous of David. He's claiming I'm letting Kaiser called David 'Dada,' but Kaiser knows David by 'David' – I would never do that to Kaiser and I would never do that to Nathan because that's unfair."

Evans went on to claim that in addition to being jealous of Eason, Griffith was reportedly not yet over her.

"Every time we talk, he doesn't even really ask about Kaiser," Evans said of Griffith. "He just asks how I'm doing and what I'm up to lately ... I don't think he is sure of his current relationship, or he hasn't let go [of me] yet."

As for Eason, Evans had nothing but good things to say.

"He's a very hard worker, and I love that about him," Evans revealed. "He doesn't care about me making money, or how much I get, he still pays his own bills, and he still gives me money for rent and everything, which I've never had any boyfriend do!"

"Jace absolutely loves him, [he] always wants to be around him," Evans added. "And he has an 8-year-old daughter that comes and spends the weekends along with Jace, so they get along very well and everyone is just really happy."
