There certainly doesn't appear to be any hard feelings between Khloe Kardashian and her ex-boyfriend French Montana.

The 30-year-old rapper performed at the Tidal X: 10/20 event at Brooklyn's Barclays Center on Tuesday, and ET cameras spotted Khloe's younger sisters, Kylie and Kendall Jenner, outside his dressing room. French also shared an Instagram pic of him standing between the famous sisters and their pals Gigi Hadid and Justine Skye. He hashtagged the photo #YoungLegends.

Meanwhile, Khloe has been looking after her estranged husband, Lamar Odom, after he was found unresponsive in a Nevada brothel over a week ago. After seeing slight improvements, including him regaining consciousness, Lamar was transported from Sunrise Hospital in Las Vegas to Cedars Sinai Medical Center in Los Angeles, California, where Khloe will be able to visit him more conveniently.

French praised the 31-year-old reality star for how she's stayed by Lamar’s side as he continues to make a “miraculous” recovery.

"Oh, man. I love her. I love her for doing what she's doing," he told ET.  "I feel like every woman should be like that. If you ever had a situation with somebody, and you get married -- you be a part of somebody's life for that long -- I feel like you just take that responsibility and do that. And I feel like every woman in the world should do that."

In 2014, Khloe and the French dated on and off but eventually called it quits. Over the summer, Khloe began dating 26-year-old NBA pro James Harden and, according to a source close to the Kardashian family, things were getting pretty serious.

"Khloe never loved French Montana. He was a rebound and someone she had a good time with," the source told ET. "The first guy she really liked after Lamar was James Harden."

That being said, Khloe and James' relationship is "taking a back seat" while she tends to Lamar.
