Honey Boo Boo and Pumpkin cannot believe their eyes.
Mama June's daughters stand by for their mom's return from California, after undergoing four cosmetic surgeries -- neck, arm, tummy tuck and breast lift -- in a preview clip from this week's From Not to Hot.
"I'm really scared that I'm not even gonna recognize who she is," admits 11-year-old Honey Boo Boo.
And indeed, when Mama June finally walks through the door, Honey Boo Boo and her sister's jaws drop to the floor.
"Oh my Lord," exclaims Honey Boo Boo.
Watch the preview clip above.
In another preview, fans also get a glimpse of the final step of Mama June's weight loss transformation -- which has taken the 37-year-old reality star to a size 4 after weighing 352 pounds.
During the clip, a noticeably slimmer Mama June, head wrapped in bandages, is helped into a wheelchair as she worries about her daughters.
"I'm glad the girls know that I'm OK," she says. "I just hope the pain doesn't last as long as it did last time."
Watch below for the post-surgery reveal.
Mama June: From Not to Hot airs Fridays at 9 p.m. ET/PT on WE tv.
