Kailyn Lowry Engaged, Jenelle Evans Single Again: Big Changes for 'Teen Mom 2' Stars

While the ladies of "Teen Mom" are saying goodbye to their on-screen lives, those on "Teen Mom 2" are prepping for another season. There is big relationship news for Kailyn Lowry and Jenelle Evans, two of the moms featured on the series- Kailyn is engaged, while Jenelle has claimed to be single yet again.

Lowry, the mother of 2-year-old Issac, has been with her fiancé Jose "Javi" Marroquin for nearly one year after meeting in Pennsylvania.

"He wouldn't give up until she went out with him," a friend told OK! Magazine. "But at first she thought he was really young, like 15, and crazy to be asking her out, but he's 19!"

Once the two finally started dating, Marroquin won her heart and has taken to Issac, which is good, considering the impact a significant other can have on a young child. Lowry's previous relationship didn't work out after she cheated on him with Issac's father, Jo Rivera.

"Javi has a great heart," a friend added. "He's kind and thoughtful and is also very patient with Kailyn and Issac. His patience is one of the many traits that she really loves about him. Javi and Issac adore each other. They get along great, and Kailyn knows he will be a great stepdad to her son and never treat him as anything but his own."

It's certainly a fresh start for Lowry, and fans could not be happier. Lowry's Twitter page is filled with well wishes and congrats as she embarks on this new journey.

In other news, Jenelle Evans has again separated from boyfriend Kieffer Delp. The two have dated on-and-off for over one year now, and it's questionable whether this "off" period will last.

"Yes it's true me and Kieffer r finally split up. I'm done," Evans tweeted earlier today. It comes after a series of discouraging messages including, "Going to lay in bed emotionally depressed. Don't have a cell phone anymore… Bye."

The new season of "Teen Mom 2" will premiere on MTV Tuesday, Dec. 6 at 10:00 p.m. ET.
