New York ( CNN ) -- Rapper Lil Wayne will go directly to jail after he is sentenced by a Manhattan judge Tuesday afternoon for a gun conviction , according to a person familiar with the case . Dwayne Carter , as he is known legally , pleaded guilty to felony gun charges in a deal with prosecutors October 2009 . He is expected to get a one-year prison sentence . His sentencing was delayed three weeks so he could get some dental work done , including removal of his diamond-studded braces . The person familiar with the case would not confirm where Wayne would serve his sentence . The plea agreement was a result of the rapper 's 2007 arrest outside New York 's Beacon Theater . According to police , Wayne had a .40-caliber pistol on his tour bus . `` It 's not his gun , they know whose gun it is , '' Wayne 's attorney , Stacey Richman , said after a hearing last month . In an unrelated case , Wayne also faces felony drug possession and weapons charges in the state of Arizona . Lil Wayne is a multiplatinum-selling and Grammy-winning rap artist . His hits include `` The Block is Hot '' and `` Lollipop , '' and his album `` Tha Carter III '' was the top-selling disc of 2008 . His latest album , `` Rebirth , '' was released last month . CNN 's Jennifer Rizzo contributed to this report .
