Machine Gun Kelly joined Jelly Roll on stage during his headlining set at Stagecoach country music festival in Indio, California on Saturday night.

The 35-year-old Wild Boy rapper — who welcomed a daughter with ex-girlfriend Megan Fox weeks ago — wore a snug white T-shirt, baring his heavily tattooed arms as he appeared at the show.

He added shredded blue and white jeans and a pair of white Converse Chuck Taylor sneakers.

The music artist, who is also dad to 15-year-old daughter Casie, wore a backwards hat and appeared to be in great spirits days after celebrating his birthday.

He and Megan, 38, welcomed their one-month old baby girl on March 27.

Their baby, whose name has not been revealed, is Fox’s fourth child.

The Transformers actress and MGK were in an on-and-off relationship for four years before most recently calling it quits in November 2024.

They appear to be co-parenting amicably — they were spotted picking up groceries together last week — but insiders have said that there are no plans to rekindle their romance.

Days ago Fox was seen waiting in a Rolls Royce while MGK entered an Erewhon.

‘The last few months alone have been difficult for her,’ a source told People about the actress last month.

‘At this point, she plans on co-parenting with Colson, but that’s it. She won’t be getting back together with him,’ it was noted.

The insider added that the actress is ‘doing great and over the moon about her baby girl.’

He wrote online, ‘She’s finally here!! Our little celestial seed. 3/27/25.’

Another source recently reported that Megan is thriving after giving birth to her only daughter. 

‘Megan has really leaned into motherhood again’ and had ‘missed’ the phase when her ‘kids were little,’ a source told Us Weekly.

‘Friends haven’t seen her this happy in years,’ the insider added. ‘She’s glowing.’
