Lookin’ good, Mama June!

For months, the former star of Here Comes Honey Boo Boo has been promising a dramatic weight loss — claiming that she’s down to a size 4 — thanks to gastric sleeve surgery and a new approach to diet and exercise; and after keeping her new look under wraps (literally) for months, we’ve finally got a look at her slimmer physique!

In the sneak peek of tonight’s episode of Mama June: From Not to Hot — which is airing at 10 p.m. on WEtv — Mama June consoles her youngest daughter, Alana (aka Honey Boo Boo) after Sugar Bear’s new wife (then fiancée) Jennifer invites the precocious 11-year-old to be a part of their upcoming nuptials.

In the emotionally charged clip, Mama June is frustrated that Jennifer would reach out to Alana directly instead of facing Sugar Bear’s ex-wife head-on.

While there’s plenty of drama in the short preview, all we can focus on is Mama June’s new look!
