Reggie Bush recently took to his Instagram to post a message many fans believed was a diss to his ex-girlfriend, Kim Kardashian.

Bush, a 28-year-old running back for the Detroit Lions started dating back in 2007, but called it quits three years later. Their romance reportedly ended due to maturity issues after a marriage was almost in question for the couple.

However, Bush has since moved on with his new girlfriend Lilt Avagyan and so has Kardashian--both welcoming baby girls into the world. But Bush posted an image on his social media account that has many believing that that the 33-year-old Keeping Up With The Kardashians reality star is still on his mind.

The image is from The Great Gatsby and is of Leonardo DiCaprio giving a toast. Bush captioned the image on Friday: "When you see someone else dealing with the BS your ex tried to put you through."

Thus far, Bush has remained quiet since splitting with Kardashian years ago. Amber Rose, who dated Kardashian's fiance Kanye West publicly accused the reality star of sleeping with the rapper while they dated.

Meanwhile aside from his personal life, Bush has been struggling on the field.

The Lions lost 37-27 loss against the Pittsburgh Steelers on Sunday after being held scoreless in the second half of the game.

Bush had 54 total yards in the game, most of them coming in the first half before he fumbled in the second quarter. After the game, Bush said that was physically fine and was benched the majority of the second half because of his poor performance.

"Probably because I fumbled the ball. You turn the ball over, that's what happens. I've been in this league long enough to know that. There is nobody to blame but myself," Bush said, via the Detroit News.
