You go, mama! Kailyn Lowry — who FINALLY revealed her newborn son’s name, Lux Russell — has totally bounced back from her birth. Welcoming her son, who is little brother to sons Isaac, 7, and Lincoln, 3, on Aug. 5, it’s clearly taken no time at all for the now mother-of-three to shed the baby weight!

The 25-year-old took to Snapchat to flaunt her enviable curves. Writing on the pic, “Got my groutfit on it,” Kail posed in front of her mirror with a messy bun on her head. Kailyn’s curves have been a hot topic since 2016 when she underwent a Brazilian butt lift thanks to celebrity surgeon Dr. Miami. And she’s clearly still showing off the results!

The MTV star has opened up about her return to fitness since welcoming her baby. In a recent Twitter post, she wrote, “Back in the gym next week,” though it already looks like she’s been working out. One person commented on her Instagram snap, “You look amazing for just having a baby! I just had twins a month ago this Saturday and still working on getting back to my pre baby weight!” Another added, “Are you sure you just had a baby? You look awesome!!” Go girl!

This weight loss snap comes shortly after the Teen Mom 2 star took to Instagram to post a photo with son Isaac and her newborn, and we couldn’t help but notice her toned figure. Watch the video below to see the pic!

Yet the reality star could be hitting the weights as a way to relieve stress. According to a new report, Kail is freaking out over the possibility of entering a custody battle with Chris Lopez, the father of her third child. A source previously told Hollywood Life that Chris’ mother encouraged him “to apply for full-time custody of her grandchild. Chris has no desire to try and take his kid away from Kailyn, but his mom is concerned about visitation rights.” This allegedly doesn’t sit well with Kailyn, who “is so shocked and disgusted that Chris would even consider trying for custody; it’s unbelievable to her,” a second insider said.

Her friends, however, don’t think there is anything to worry about, “and they keep reminding her to stay strong and just focus on her children. But, that said, it’s still really upsetting and frightening, and it’s really the very last thing she needs to be dealing with right now. Kailyn’s trying to defuse the situation by throwing love at it. She’s being super sweet to Chris’ mom and trying to involve her as much as she can in the baby’s life, and hoping that by doing so she’ll come around and see what a great mom Kailyn actually is.” The 25-year-old shares Isaac, 7, with ex-boyfriend, Jo Rivera, and Lincoln, 3, with ex-husband Javi Marroquin.

Teen Mom 2 airs Mondays at 9 p.m. EST on MTV.
