Lamar Odom‘s giving a whole new meaning to the nickname “dollface” … ’cause he just ordered his own custom sex doll — and, he wants it to look like his ex Khloe Kardashian!

The former NBA star went on a NSFW Willy Wonka-level tour of RealDoll‘s Las Vegas facility Tuesday … full of totally nude female sex dolls hanging on hooks and huge realistic male organs — and, Lamar got to touch everything in the facility.

Ya gotta watch the clip … Lamar’s walking through the facility — picking up dildos and whipping them around before copping a feel of one doll’s boobs, touching her all over and saying it almost makes him want to design women’s fashion.

Lamar’s manager, Gina Rodriguez, tells TMZ … Lamar first saw RealDoll in a news story about a month ago — and knew instantly he needed to get one for himself.

We’re told Lamar was in Las Vegas this week for his birthday … and, he decided it’d be the perfect time to go find himself a silicone GF — and, sounds like he did ’cause the money changed hands and the doll is under construction.

The dolls usually go for between $8K and $20K, but we’re told RealDoll cut Lamar a deal — though we don’t know what kinda discount he got.

RealDoll doesn’t just do prepackaged dolls BTW … Lamar opted for a custom order — picking and choosing his new bang buddy’s lady bits.

We’re told he wanted the doll to have voluptuous curves … and based the face on his ex-wife Khloe Kardashian’s. Gina tells us Lamar thinks this Khloe-like sex doll will be perfect — because he can do whatever he wants with her sexually. No word on how Khloe’s feeling about this new tribute.

Khloe and Lamar were married from 2009 to 2016 … but Lamar’s drug and alcohol abuse and infidelity ultimately tore their marriage apart. They don’t have any kids.

Like we said, the doll isn’t finished yet … but, we’re told Lamar should get it before the holidays — perfect for a kiss (or more) at midnight on New Year’s Eve!
