lamar-odom *The end of a marriage affects people in different ways.

That may explain why five months after his estranged wife, Khloe Kardashian filed for divorce, Lamar Odom is reportedly packing on the pounds. Media sources note that the 6 ft. 10 in athlete was spotted looking tired and out of breath while sporting a noticeably larger stomach on Saturday as he came back from a workout.

Wearing a blue long sleeve shirt, which was tucked into a pair of shorts, Odom was carrying a couple of sweatshirts over his left shoulder. (Scroll down for a link to the pics) News of the 34-year-old basketball player’s physical look comes as Khloe tries to fully move on from her marriage with rapper French Montana.

The pair were seen at the Floyd Mayweather Jr. versus Marcos Maidana boxing match in Las Vegas on May 3 before going to the Rehab pool party at the Hard Rock Hotel the following day.

Despite the fun Khloe is having with Montana, RadarOnline.com reports that the divorce is preventing the reality TV star from fully enjoy her new relationship.

“While Khloé is very happy with French – because he treats her like a queen – she isn’t fully able to enjoy it because Lamar still hasn’t submitted a response in their divorce proceedings,” a source told Radar. “It has been ages since Khloé has been going to clubs and just having fun.”

After four years of marriage, Khloe filed for divorce from Odom on December 13 amid allegations of him cheating and using drugs. Odom, meanwhile, appears to be rebounding professionally by recently signing with the New York Knicks.
