Khloe Kardashian and French Montana appear to still be basking in the glow of stealing the spotlight from boxing champ Floyd Mayweather during his recent Las Vegas title night defense against Marcos Maidana.

HollywoodLife.com reports Lamar Odom's estranged wife walked into the fight venue arm-and-arm with the bad boy rapper she has recently been seen all over the country wining and dining with.

Kris Jenner not a French Montana fan?

The website adds the 29-year-old Keeping Up With The Kardashian star was sure to show off the new curves born of her dramatic weight loss, wearing a spandex tight-dress and newly tinged blonde-tipped hair.

After Mayweather recorded his majority victory-decision, HollywoodLife reports the pair ventured off to Diddy's high-profile post fight gathering at the Hard Rock Hotel, where witnesses told the website "they were 1,000 percent affectionate."

"He kept his hand on her back and was very attentive to her and helped her through the crowd, holding her hand," the source added of the couple's Sin City evening.

Lamar Odom, Khloe Kardashian finally over?

The newly minted couple ended their night dining at 35 Steaks + Martinis, where other sources told the website Montana spent the rest of the night referring to the reality TV star as "baby" and appearing totally engrossed by her.

Citing irreconcilable differences, the 29-year-old Kardashian filed for divorce from Odom last December following a summer during which he was arrested on DUI charges, publicly accused of cheating with at least three different women and being briefly confined to a drug treatment facility.
