Megan Fox Seen with Machine Gun Kelly as Husband Brian Austin Green Shares Cryptic Post on Her Birthday

Could Megan Fox and Brian Austin Green be on the outs?

The Transformers actress, 34, was spotted driving around and picking up food in Calabasas, California, with rapper Machine Gun Kelly on Friday.

Both Fox and the rapper, 30, have been cast in Midnight In The Switchgrass, although production on the film has been halted due to the coronavirus pandemic, Deadline previously reported.

A rep for Machine Gun Kelly did not immediately respond to PEOPLE’s request for comment.

One day after the outing, the Beverly Hills, 90210 actor, 46, shared a cryptic message on social media, which coincided with his wife’s birthday. “Eventually butterflies get bored sitting on a flower for too long,” he wrote alongside a photograph of a butterfly on a flower. “They start feeling smothered. It’s a great big world and they want to experience it.”

Reps for Green and Fox also did not immediately respond to PEOPLE’s requests for comment.

Fox and Green, who share sons Journey River, 3, Bodhi Ransom, 6, and Noah Shannon, 7, was also seen at a Calabasas parking lot last month, transferring their children from one parent’s car to another, according to the Daily Mail. (Green is also a father to son Kassius, 17, from a previous relationship with ex Vanessa Marcil.)

Both stars have also been photographed in recent weeks without their wedding rings.

Most recently, Green was seen on Saturday without his ring, while visiting the same coffee shop Fox and the rapper had been to the previous day.

Fox and Green have had their fair share of ups and downs over the years.

After first meeting on the set of Hope & Faith in 2004, when the actress was 18 and Green was 30, the pair dated for about two years, before initially getting engaged in November 2006.

Over a year after calling it off in February 2009, they got engaged again and tied the knot soon after in 2010. However, Fox went on to file for divorce in 2015, citing irreconcilable differences.
