'Teen Mom 2' Chelsea Houska Baby with Cole DeBoer: MTV Star Wanted New Addition for a Long Time!

Teen Mom 2 star Chelsea Houska recently added a new addition to her family with boyfriend Cole DeBoer, but it didn't come as a surprise to them as it did to the MTV fans.

As MStarz reported, the reality couple got a new baby pig as a pet. Apparently, the MTV mom had decided to get the piglet a long time ago.

"Chelsea has wanted a pig since she was little," a source told Radar Online. "She put a lot of research into it. When she bought her new home, she knew she would get one eventually."

The South Dakota native showed how much in love she is with her hunky man by purchasing the adorable animal with him.

"Cole has always wanted a pig, too, so they decided to get one together," the source said.

The little swine, named Pete, will also live in Chelsea's house with daughter Aubree and a Great Dane named Phil.

It seems as though the TM2 star is getting closer to an engagement with her traffic controller boyfriend. She doesn't want anything to ruin the relationship -- even meeting baby daddy Adam Lind on camera.

"Chelsea made it clear that Adam and Cole were not going to hang out for a dramatic scene," a source told Radar. "It would never happen in real life, so why force it?"

"Adam is not a part of Chelsea's life, so it's not important," the source continued.

Do you think this means Chelsea and Cole will finally get engaged soon?
