*Romance rumors sparked over the weekend when Khloe Kardashian was seen heading to the gym with Los Angeles Dodgers player Matt Kemp just hours before filing for divorce from her husband of four years, Lamar Odom, on Friday.

“They are just friends and have been for a long time,” an insider revealed to People Magazine.

“Khloé is absolutely heartbroken right now (over Lamar) and dating someone is the last thing she’s thinking about,” the source added.

Another insider told the Daily News that the reality starlet and Kemp are “not dating.”

While the duo have yet to cross the line of “just friends,” a Kardashian source told to People, “it could be heading (that way) in the future.” However, “Khloé wasn’t spending time with him when she was still with Lamar. She absolutely wasn’t. People need to remember that she and Lamar haven’t lived together since June.”

As of late, the 29-year-old TV personality and her athlete pal have been hitting up music scene together.

On Nov. 25, Kardashian and Kemp were photographed in the VIP section of a Drake concert. The two also attended a John Legend show on Dec. 1 and a Jay Z concert on Dec. 9.

Kemp fueled the rumor mill when he posted an Instagram pic of the Kardashian family Christmas tree from inside their Calabasas home on Thursday.

“Best time of the year!! It’s gonna be a Cali Christmas this year,” he wrote.

Kemp famously dated singer Rihanna in 2010 shortly after she split with rapper Chris Brown.
