Mackenzie Douthit, 18, isn’t going to be a single mom for much longer — she’s engaged to her long-term boyfriend and baby daddy Josh McKee!

Mackenzie announced the good news on Jan. 8 via Twitter when she shared an Instagram photo of her new engagement ring and wrote simply, “I said yes.” This is the second time Josh popped the question — the couple were previously engaged last year, but called things off in October 2012.

Mackenzie & Josh Featured On ’16 & Pregnant’

The high school senior was selected as part of MTV’s new cast of moms for the brand-new series Teen Mom 3. Mackenzie, a popular Oklahoma cheerleader was a fan favorite during the fourth season of 16 & Pregnant.

Mackenzie is still a high school student — back on the cheerleading team — who is also enrolled in cosmetology school. Josh was featured on 16 & Pregnant riding horses in the rodeo for extra cash, but he is currently a member of the Marine Corps. The couple will move to San Diego, Calif. where he is being stationed.

Mackenzie’s Dream Wedding

Even though they haven’t set a date yet, Mackenzie revealed to Us Weekly the details of her dream wedding in the spring when she was engaged the first time.

“We want like hay bales for people to sit on, and we want it in a barn, and we want to ride up on horses. We’re very country people,” she said. “We went to prom in camouflage last year. And we took pictures with like guns, holding them. I was four months pregnant, but…”

Alexandria Sekella‘s ex boyfriend Matthew McCann fell off a cliff on Nov. 26, and is now critically injured. Matthew’s near-fatal accident occurred after a night of partying and drinking at Pennsylvania nightclub The Knob, when he left the bar and wandered off a cliff. He fell twenty feet. Teen Mom 3 star Alex, who has an 18-month-old daughter named Arabella with Matt, blames his accident on substance abuse problems.

Alex and Matt split up shortly after Arabella’s birth, and the pair barely speak, as Matt has struggled to control his drinking and drug abuse problems. Alex, 18, has more or less raised Arabella on her own, as she does not allow Matt to be involved in her life. On Nov. 27, Alex tweeted, “She’s [Arabella] not allowed anywhere near him.”

Matt’s tragic accident occurred after his night of partying, and Alex said: “All I know is he was partying with friends and he walked off a cliff and fell 20 feet. He’s in ICU. He can’t move”.

Alex took to Twitter shortly after the incident to show her concern for Matt: “Matt was involved in a horrible accident [he] is in ICU please keep him in your prayers.” However, her attitude has changed overnight, as on Nov. 27 she spent the day bashing Matt to her followers.

She tweeted “Matt’s not strong willed he’s a phony a fake a follower and a poser” and “my family just calls him sperm donor”. She also called him a “waste of space”. While Alex’s frustration’s are valid, it’s a little harsh for her to diss him right after his horrifying accident.

What do YOU think, HollywoodLifers? Is Alex right to be mad at Matt, or should she show some compassion?

MTV just wrapped the original series of Teen Mom in September, but a whole new group of moms plucked from the fourth season of 16 & Pregnant will be making their way to the small screen.

MTV will officially unveil the final cast on Nov. 3 during a taping of the Teen Mom 3 reunion in New York City with Dr. Drew. According to Onset Productions, the company that’s hosting the reunion, the ladies will discuss “new and old loves, schooling, legal situations, and their children’s terrible twos.”

Although the network hasn’t yet confirmed the four new moms, the newest group of young mothers are believed to be Briana Dejesus, Mackenzie Douthit, Katie Yeager, and Alexandria Sekella, according to Wetpaint.com.

RadarOnline confirmed Mackenzie and Alexandria back in May, but the final two spots were up for grabs — until Katie posted photos of her daughter Molli‘s first birthday to her Facebook account with visible camera crews in the background.

Briana also gave a not-so-subtle hint on social media about her future reality career. ”Don’t be mad when you start seeing more of me on ur television screen,” she wrote on Twitter.
