Los Angeles, California - Could wedding bells be ringing soon?

Megan Fox (35) and her boyfriend Machine Gun Kelly (31) have kept the rumor mill swirling about their hot and heavy relationship.

Kelly accompanied her boo as he rehearsed for the 2021 MTV Video Music Awards on Wednesday.

An insider revealed to Us Weekly that the Transformers actor reportedly wore a "ring on that special finger" while watching her honey on stage.

Also, the source teased a possible "surprise announcement" to come during the rapper's VMAs performance this Sunday night.

Kelly will unveil his new single Papercuts alongside drummer Travis Barker (45), who whom he got matching tattoos to promote his new album.

But will he also reveal something new about his love life?

Fox and Kelly met while filming the action thriller Midnight in the Switchgrass in May 2020 and quickly felt sparks fly.

In July 2020, they made their new couple status official on Instagram and have been unable to keep their hands off each other since. They certainly make no secret of their sometimes bizarre displays of affection!

Whether it's on social media or in interviews, the two never miss an opportunity to express their "twin flame" romance.

In January, speculation about a possible engagement was rife after Megan was seen wearing a huge ring on her finger in New York.

Shortly after, the actor took to Instagram to share a picture of the bling that read "F*** you," and added a matching eye-rolling emoji.

About a month later, a source told Us Weekly that the star is "in no rush to get married again" following her failed marriage to actor Brian Austin Green (48).
