Mama June Shannon has once again packed on the pounds even though she went through a lot just to achieve her life-changing, 300-pound weight loss.

A new teaser trailer for “Mama June: From Not To Hot” Season 3 was released on Thursday via ET Online, and the clip shows Mama June admitting to gaining some weight again. The trailer reveals that Mama June’s family are actually worried because of her weight struggles.

Mama June herself addresses the weight gain in the trailer. She admits that she’s been gaining weight because she’s been eating a lot. However, she said that she’s making sure that she won’t be coming back to her old self.

“I’ve gained a little bit of weight back but I’m not ever going to be 450 pounds again,” she says in the video clip.

But it would be so hard for Mama June to keep that promise as she’s seen devouring a giant cake, some ice cream and a whole lot of fried foods in the snippet.

Last August, Mama June dropped a bombshell when she confessed that she gained 50 pounds back after her massive transformation, as pointed out by Radar Online.

Interestingly, there could be another reason why Mama June has suddenly gotten a huge appetite. The trailer hints at Mama June experiencing a delay in her period. This leads the reality star to ponder upon the possibility that she and boyfriend Geno Doak could be having a baby together.

Interestingly, to help Mama June focus on her weight loss program, she and arch-nemesis Jennifer Lamb will be having a slim down showdown, according to Access.

The healthy competition was actually teased in the clip Honey Boo Boo’s mother shared on Instagram late last month. In the video, Mama June is seen doing some intense exercises. At the end of the clip, Mama June receives some news that someone is joining her weight loss program.

Now that it’s confirmed that it’s going to be Honey Boo Boo’s stepmom, fans can expect Season 3 to be more exciting.

Meanwhile, the all-new season of the WE tv series will also follow Alana’s Hollywood journey. The 13-year-old joined “Dancing With the Stars” and teasers for the upcoming season show her rehearsals and preparations for the dance competition.

“Mama June: From Not To Hot” Season 3 premieres March 15 at 9 p.m. on WE tv.
