Lamar Odom appears to be heavier following his split from Khloé Kardashian.

The 29-year-old Keeping up With The Kardashians star filed for divorce from the 34-year-old professional basketball player on 13 December, after four years of marriage, citing irreconcilable differences.

Odom was recently spotted coming from a workout in Sherman Oaks, California, and was noticeably bulkier than he has been over the years. The 6'10 athlete, who was wearing a blue long-sleeve shirt, and shorts, had put on excessive weight around the abdomen.

This comes after reports emerged that Odom is not ready to sign divorce papers and is still hoping to win Kardashian back.

"Lamar wants Khloe back. He does not want to end the marriage, and that's why he won't sign the divorce papers. He just won't let her go. He's sober and back on track now — and thinks he can get her back," an insider told Life & Style Magazine.

Kardashian and Odom's marriage first hit the rocks when a video surfaced, showing him rapping about how he cheated on her. He was also allegedly not willing to take professional help for his drug addiction.

However, Kardashian has moved on with rapper French Montana, and it's taking a toll on Odom.

"Khloe is out in public with new guys all over them and it is killing Lamar," a source told Radar Online. "Yeah, he was totally with other women [first], but he doesn't want Khloe to shove it in his face that she is moving on. Lamar is jealous and gets mad when she refuses to talk to him."
