Khloe Kardashian Lamar Odom Wedding This Weekend!

Wow, that was fast! After about a month of dating, Khloe Kardashian will marry her boyfriend Los Angeles Lakers forward Lamar Odom, this Sunday.

"It's at a private residence in LA," a close friend of Khloé's tells Life & Style. "The wedding planner, photographer, groomsmen and bridesmaids have all been chosen."

"It's chaos at the Kardashian household!" the friend adds.

And, of course rumors are swirling that Khloe is currently knocked up. But sources say, she's not pregnant, just "in love."

No word yet on whether Khloe's race to the altar will be documented for her E! reality show Kourtney and Khloe Take Miami.

Odom is Khloe's third pro athlete beau. Last year, she dated basketball player Rashad McCants and footballer Derrick Ward.

Odom has two children with a former longtime girlfriend named Liza Morales. They have a 10-year-old daughter and a 7-year-old son. They also had a second son together who passed away from SIDS a few years ago.

Odom recently signed a four-year, $33 million contract with the Los Angeles Lakers and helped the team win the NBA Championship in June.
