Machine Gun Kelly — born Colson Baker — told fans he was “locked in” his relationship with Megan Fox on the latest episode of “Thirst Tweets” for BuzzFeed Celeb.

After reading a tweet that said, “Machine Gun Kelly i just wanna let you know am free this sunday to go on a date just let me know if ur free sunday cause i am free and would like to take you on a date [sic],” and responded by gently letting the fan down.

“I’m locked in already right now,” he responded with a smile. “No dates for me. Probably ever.”

Later in the video, he read a tweet, “i would let machine gun kelly suck my toes maybe [sic],” and retorted with, “Like I said, I’m only sucking one pair of toes.”

The “Project Power” star, 30, met the “Transformers” star, 34, while filming Randall Emmett’s “Midnight in the Switchgrass” and rumors of a romance began in May.

Fox’s estranged husband, Brian Austin Green, announced that the couple split the same month. They share three children: Noah, 7, Bodhi, 6, and Journey, 4.

Fox appeared in his music video for “Bloody Valentine” later that month, with the singer declaring that he was “in love” in June.

The couple became Instagram official in July and Fox relayed the same sentiment on Instagram in August.

Green, 47, took a jab at the couple, posting a collage of his sons, including his 18-year-old Kassius with Vanessa Marcil, with the same caption — “Achingly beautiful boys…… My heart is yours.”

Not surprisingly, MGK didn’t read any tweets relating to that.
