Machine Gun Kelly lost $50,000 gambling in Las Vegas.

The 34-year-old rapper, who says he has been sober for a year after secretly checking himself into rehab – and who has experienced ups and downs in his relationship with his 38-year-old girlfriend, actress Megan Fox, made the confession during a performance alongside 39-year-old singer Jelly Roll as the country star opened for Morgan Wallen at Allegiant Stadium in Sin City.

MGK – born Colson Baker – told his fans about losing a fortune: “I lost $50,000 at the blackjack table tonight.”

The artist, who is said to be worth $25 million, then jokingly asked the crowd for help. In a video shot by a fan, he said: “Y’all need to stream ‘Lonely Road’ and make the money back.”

MGK then joined Jelly – real name Jason Bradley DeFord – for a rendition of their song “Lonely Road” and a duet of Jelly’s “Need a Favor.”

The singer also told fans during her performance: “I love you all. Thank you, Jelly, for letting me be a part of it.”

Jelly said, “Make some noise for one of my best friends, MGK. Thanks for coming, baby. I love you, Bubba. I love you so much, Bubba.”

The pair’s “Lonely Road” is a take on John Denver’s classic “Take Me Home, Country Roads,” which was released on July 26 and peaked at number 33 on the Billboard Hot 100.

MGK announced the song’s release in an Instagram post showing him with Jelly, along with the caption, “Jelly you are a living, breathing bada** and a kindred spirit who showed me the path to redemption and what it looks like to believe in yourself against all odds.”

“From our argument 12 years ago to what we’ve released that I believe will be the biggest hit of our career, I’m proud to call you my brother and life feels better knowing you have my back.”

MGK recently told Jelly’s 44-year-old wife Bunnie Xo – real name Alisa DeFord – on her podcast “Dumb Blonde” that he is “completely sober” and “hasn’t eaten anything.”

He said: “I don’t drink anymore. I haven’t had a drink since last August. That was the first time I went to rehab.”
