June "Mama June" Shannon is about to turn into mama bear!

The reality star decided to go embark on a weight loss journey after her ex Mike "Sugar Bear" Thompson announced that he’s getting married — which will be documented on her new WEtv docuseries Mama June: From Not to Hot. But even though she doesn’t want Sugar Bear back, she’s not ready to see him move on — and she especially is not happy about his new fiancée meeting their daughter, Alana “Honey Boo Boo” Thompson!

During this week’s episode, Sugar Bear took Alana out to lunch to meet his soon-to-be wife for the first time, and the 11-year-old was so nervous about meeting Jennifer Lamb for the first time.

“Hi Alana, I’m going to be your new step-mom!” Jennifer told Alana, and Alana made a face at her.

“When Mama hears I met Jennifer, she’s going to lose it,” the former pageant star revealed in her confessional. “So I’m not gonna tell her.”

But while the episode was airing, Mama June was watching along and she laughed when she saw the way her daughter reacted to meeting her new step-mom.

“Sugar Bear [is] trying to be father of the year with his new girl. Alana study her like b—tch who are you,” the 37-year-old wrote on Twitter, adding two laughing emojis.

Mama June underwent weight loss surgery in order to work on her revenge body, so she could show up to Sugar Bear’s wedding with a smoking hot date and show him what he’s missing. She attempted to get back into the dating pool after her 17-year-old daughter Lauryn “Pumpkin” Shannon and niece Amber set her up with a profile on RedneckandSingle.com — and she went go-kart racing with a “cute” guy named John even though she’s legally blind.

Fans were shocked when Mama June revealed that she’s visually impaired, and one viewer tweeted at Mama June, dissing her ex.

“Legally blind? Now I see why you were with Sugar Bear!” the fan wrote, and Mama June wrote back with some major shade.

“I think I have to agree,” she responded.
