This girl is on fire.

Megan Fox looked almost unrecognizable with fiery red hair, which could be a wig, during a rare outing with Machine Gun Kelly for lunch at Soho House in New York Monday. 

The “Jennifer’s Body” star stepped up her style just in time for fall with the red hot new ‘do — but, unlike the currently trending “cowgirl copper” or her usual long auburn locks, her hair was completely crimson.

Fox showed off the blunt cut bob with bangs while wearing a black and white polka-dotted minidress and on-trend chunky black and white platform loafers. 

The “Night Teeth” actress, 37, wore plenty of jewelry to match her rocker beau — showing off a gold choker and a silver chain with a black amulet on the end along with gold rings. 

Kelly, whose real name is Colson Baker, looked equally fall-ready in oversize, shiny silver sweatpants. The “Bad Things” singer paired the Y2K-inspired pants with a tan tank top and layers of silver necklaces. 

The singer, 33, and Fox have had quite the tumultuous relationship since they first got together in 2020 while filming the movie “Midnight in the Switchgrass.” As of late, the on-again couple have rarely been seen out for their usual PDA-heavy dates.

In February, Fox ditched her engagement ring following her cryptic social media posts that seemed to call out the “Bloody Valentine” rocker for cheating.

However, while the couple seems to be back on track at the moment, their wedding planning has been paused. 

For more Page Six Style …

Though the “Transformers” star may not be walking down the aisle anytime soon, she also hasn’t let the ups and downs of her relationship status stop her from having a sexy summer.

Fox’s Instagram has been heating up with loads of photos, including steamy beach pictures and fiery forest photos that saw her free the nipple and expose her behind.

Now, with her new scarlet hair, even though it may be temporary, she’s ready for an equally ferocious fall.
