Chelsea Houska and Cole Deboer are getting married at the end of this year and as their wedding date approaches, the Teen Mom 2 star is becoming more and more strict with her diet and exercise routine.

In an effort to get into the best shape of her life, Houska has been working out hard and when it comes to her diet, she isn't allowing herself to indulge in unhealthy eating habits.

Houska became engaged to Deboer in November of last year after just over a year of dating.

Months ago, during an interview with PEOPLE Magazine, Houska spoke of her love for her fiance and dished on their wedding and baby plans. 

"Cole is such a great guy, all the time," Houska told the magazine. "He's so calm, even when I'm worried about something. He's just so great to me and to Aubree, so to be able to know that I can have that person forever is the best feeling. That's what I've always wanted – a family – and I feel finally like that's exactly what I have."

"It's going great so far," Houska continued of wedding planning with her man. "We both want a small wedding... He works a lot so I'm kind of the one that is going [to all the appointments,] but I don't make any decisions without running it by him first. We have the same taste and the same ideas, so far it's been really easy."

As for having children, Houska added, "We're just going to get through this wedding, and then hopefully have some babies!"

"I feel like I want three more, but everyone always looks at me crazy when I saw that, so maybe I'll have one more and then we'll decide exactly how many!" she said. "I think I would want a boy somewhere in the mix."
