Now we know what it takes to make Rob Kardashian come out of hiding.
The troubled reality star, who has scarcely been seen or heard from since ditching the Kim Kardashian-Kanye West wedding in May, has responded to the scathing interview ex-girlfriend Adrienne Bailon recently gave to Latina Magazine.
In the cover story, Bailon says Kardashian "strategically" cheated on her and that her career was "hurt" by her association with his family.
But Kim and Khloe Kardashian quickly came out and took Bailon to task, with the latter saying Adrienne has some nerve to "kick [her] brother when he's down."
Last night, Rob retweeted this message and wrote along with it three simple letters: FDB.
