Machine Gun Kelly celebrates 34th birthday with Megan Fox by his side during ... trends now

Machine Gun Kelly had ex-fiancée Megan Fox by his side during his 34th birthday celebrations at his home on Monday.

The rapper-turned-rocker — born Colson Baker — shared snaps from his star-studded birthday bash, and one of them included the Jennifer's Body star, 37. 

They both flashed big smiles for the camera, with the musician sitting on the ground amid a sea of candles and Megan crouching next to him. 

'Genre: birthday,' he captioned the carousel of photos. Other attendees at Kelly's birthday celebration included Post Malone, Tiffany Haddish, Evan Ross, rapper Mod Sun and Amber Rose. 

It comes a month after Fox confirmed the end of their engagement, and recently advised ladies not to 'waste' their energy on men.  

And on Wednesday a source told Us Weekly that Megan 'is reevaluating everything in her life' and that 'It was getting toxic between them and they were fighting a lot.'

The insider went on to say that the actress 'wants her freedom right now' and that she told him she 'wants space.'

Another source told the publication that the pair's 'dynamic is a roller-coaster, and things change all the time.'

For MGK's birthday Megan rocked light blue tresses, and sported a black corset with oversized black baggy pants. She completed the outfit with a black jacket and sneakers.

The mother-of-three accessorized with layered necklaces.

Meanwhile MGK rocked a blue t-shirt with rapper Nelly on it, and matched Megan in oversized black pants and sneakers.

In one snap he was seen carrying his black birthday cake, which featured a number of colorful crystals and a dragon on top of it.

MGK also shared a snap with his daughter Casie, 14, and famous pal Post Malone, 28, who were seen flipping the bird for the camera. 

The Rap Devil hitmaker shares Casie with ex Emma Cannon, who MGK dated briefly before his rise to fame.

Another picture showed MGK and Malone — who is gearing up to release his much-anticipated first country album — in deep conversation. In yet another snap he was seen jamming out on his guitar while surrounded by friends.
