Three letters to break the silence on a ruined relationship.

In a seemingly moot move to defend himself, Rob Kardashian had three letters for former girlfriend, Adrienne Bailon - "FDB", the shortcut for "f**k dat b***h".

Retweeting his older sister Khloe's post, Rob Kardashian took to Twitter to somehow comment on Bailon's remarks on how she continues to regret her association with the Kardashian clan and, how former beau, Rob, was so "disloyal" to her, planning his trysts with other women in advance.

Bailon revealed her feelings in the recent issue of Latina magazine.

She shared that she regretted appearing on "Keeping Up with the Kardashians" and letting the public see how her relationship with Rob played out. She reiterated, "To be stuck with that Kardashian label, that was so hurtful to me and to my career."

She also admitted that to this day, people blame her for ruining Rob's life. She said they were still so young when they met.

Rob kept quiet despite older sister Kim taking to social media to say that the only reason why Bailon was interviewed in the first place was because of her association with the family. Kim also said she thought she and Bailon "were cool" before the interview and that the Cheetah Girl shouldn't be kicking her brother when he was down.

However, after Khloe tweeted the three-letter post, Rob was quick to retweet it to his more than 5 million followers.

Although Rob only had three letters for Bailon, he had more to say to rapper Nicki Minaj after all the dirt regarding his former relationship resurfaced.

Minaj tweeted out to her fans and posted, "U guys give me so much life. Thank you."

Kardashian, an apparent Nicki Minaj fan, retweeted the rapper's message, adding the reply, "GOD BLESS YOU boo boo."

Minaj saw Kardashian's tweet and replied with "hey boo" and a smiley face.
