Lil Wayne and Christina Milian have split up after a year of dating ... TMZ has confirmed.
Weezy and Milian were first rumored to be hooking up in July 2014, but only recently began publicly acknowledging their relationship.
Sources close to the ex-couple blamed their busy schedules for the break-up, and we're told neither's pointing fingers. In other words ... it's amicable.
Wayne and Christina released some tracks together earlier this year, and it's unclear how the split will affect their professional relationship. She's a Young Money artist, but of course ... it remains to be seen how long Wayne will be with his label.
