According to a report, Megan Fox and Machine Gun Kelly have ended their on-again, off-again romance just weeks after announcing they are expecting their first child together. The couple was together for over four years.

TMZ was first to report the news. Representatives for both did not respond to PEOPLE’s request for comment.

Fox, 38, announced her pregnancy on Instagram on Monday, November 11, tagging Kelly in the photo showing off her baby bump. The child will be the fourth for Fox and the second for Kelly. Fox is already mother to sons Noah, 12, Bodhi, 10, and Journey, 8, with ex-husband Brian Austin Green, while Kelly is father to daughter Casie, 15.

The Lonely Road artist, 34, and Fox first met while filming Midnight in the Switchgrass in March 2020. In May of this year, the couple made their relationship public after Fox appeared in Kelly’s “Bloody Valentine” music video.

In January 2022, the actress announced the couple’s engagement on Instagram.

Their relationship had ups and downs. Shortly after the 2023 Grammys, an insider told PEOPLE that the couple had an argument and Fox was “very upset” and “won’t be speaking to Kelly.” In March of this year, Fox attended the Vanity Fair Oscars afterparty alone — and without an engagement ring.

However, in May 2023 they will pose together on the red carpet again. Still, a source told PEOPLE at the time that Fox “still seems hesitant” about planning a wedding.

However, the relationship continued and Fox revealed her heartbreak in November 2023 when she publicly announced that she had suffered a miscarriage. Kelly later sang about the loss in his song “Don’t Let Me Go.”

A source told PEOPLE just in November that the couple was “very excited” about their pregnancy and “can’t stop talking about the baby.”

“They are very excited. “(Kelly) is basically telling everyone he knows,” the insider said, adding that the engaged couple is “doing well” and “focused on the baby right now.” Then she realized it didn’t look like they were going to get married before the baby came.
