Young Buck is currently behind bars serving an 18-month sentence, but was noticeably absent from his Twitter page, which he recently explained.

"Dear Fans, I was in the hole 4 the last 2 months, so it's been slow on the mail, so Im back to writing y'all this week! I appreciate y'all!"

While Buck didn't go into detail about why he was put in solitary, but Wendy Day of Rap Coalition revealed that the rapper was locked up for doing a freestyle over the phone.

"@RapCoalition: Ladies & Gentlemen, @youngbuck is finally out of the hole for doing a freestyle over the phone for y'all."
