It could have been awkward if "Keeping Up with the Kardashians" star Khloé Kardashian had accompanied new boyfriend James Harden to Meek Mill's concert on Saturday at Drai's Nightclub in Las Vegas because her husband Lamar Odom was also in attendance.

Following the release his second studio album, "Dreams Worth More Than Money," which is currently the number one album in the U.S., Mill performed a full-length concert at Drai's Beachclub on July 11 while both Harden and Odom watched the show, reports TMZ.

Harden and Odom did not seem to notice each other. Each hung out with friends on opposite sides of the VIP area.

Rumors that Kardashian was dating the Houston Rockets star surfaced earlier this month after the two were spotted hanging out poolside at the Encore Beach Club in Sin City.

Most recently, the NBA shooting guard and the former "Kourtney & Khloé Take the Hamptons" star enjoyed a spin class together at West Hollywood's Cycle House followed by dinner at E.P. & L.P. in Beverly Hills. The couple shared a kiss following dinner that was caught on video.

Though she is dating Harden, Kardashian remains legally married to Odom. The two have been separated since late 2013 when she filed for divorce, but she still sees the former LA Lakers star on occasion.

It was reported last week that Kardashian is committed to helping her estranged husband kick addiction to black tar heroin. The former two-time NBA champion is reportedly hooked on the drug, which he has regularly used since traveling to Las Vegas about two months ago.

Kardashian was with Odom last month to comfort him following the death of his best friend, Jamie Sangouthai, who had died of a drug overdose. We know this for a fact because Kardashian's friend Malika posted an Instagram picture on June 14 of herself, Kardashian and Odom, as the friends came together to grieve the loss of Sangouthai.
