Rob Kardashian let the world know on Instagram that he has a huge crush on Basketball Wives LA star, Draya Michele.

The only Kardashian brother took to his social media account to post a sexy image of Michele in honor of "Woman Crush Wednesday", writing,"#wcw YAAAAAASSSSSSS lol @sodraya,"

The image is one of Michele's photos she did in a recent photoshoot, showing her braless under a sleeveless white t-shirt.

Rob, 27, has been out of the media spotlight for some while, as he recently deleted all of his posts on Twitter and Instagram.

According to reports, he has been dealing with some serious personal and weight challenges, which caused him to miss out on the family's recent vacation to Thailand.

"Rob was drinking a lot of Sizzurp, and that's one of the reasons he gained so much weight," a source said. "Rob is well past the point of desperation and now is just flatout miserable. He wants to be the star of the Kardashians for once in his life, but right now he feels like he's bringing the entire family down."

He reportedly even checked himself into a rehab facility.

"Rob has been checked into The Meadows for about a month for substance-abuse issues," a source told Star magazine."He's been feeling stronger and more relaxed without the incessant berating from everyone. I would love to see him show up a changed man at Kim's wedding and gain some independence."

Rob's sister, Kim will be getting married to Kanye West soon, and he is planning on attending the wedding.
