Now that Rob Kardashian is engaged to be married to his fiancé Blac Chyna, his brother-in-law Lamar Odom, who's had his fair share of stuggles in marriage, himself, has a few words of advice for him.

Shown in a preview for an upcoming episode of Keeping Up With the Kardashians, Lamar spoke on Rob's decision to marry Chyna after six months of dating, reports the Daily Mail.

"I just hope he's focused," he said. "Marriage ain't easy."

Khloé, in response, added, "It's not? Your marriage wasn't easy?"

Khloé and Lamar can relate to Rob and Chyna's situation a bit as they famously wed in 2009 just after one month of dating. The reality star filed for divorce in 2013 and again, more recently, on May 26.
