The reality star filed for divorce from her husband of four years in December following allegations of the basketball player's infidelity and drug abuse, but sources claim the pair haven't given up hope on their marriage just yet.
An insider told Us Weekly: ''They're talking all the time. It's not over yet.''
The 29-year-old brunette has just moved into Justin Bieber's former Calabasas, California, mansion - which cost her a cool $7.2 million - and is said to be building an inside basketball court in her new home, which Lamar hopes could be a sign of a potential reconciliation.
Another source added: ''Her installing a basketball court really says something. He thinks he could get Khloe back.''
The 34-year-old sports star is currently back in the US after quitting Spanish basketball team Laboral Kutxa due to an injury.
Khloe recently admitted she found it heartbreaking watching her marital troubles play out on her family's E! reality show, 'Keeping Up With The Kardashians'.
She confessed: ''It's definitely not anything I'm through. I'm going through it, but I'm not through it. It's really hard to watch yourself on TV too.
''It's definitely different in that the world has to watch too. It's definitely not the easiest thing to do but it's my life now I guess.''
