One of hip-hop's more on-off-on-off relationships has taken another twist. TMZ has exclusive pics, and the story: "Nas and Kelis insist they aren't getting back together, but they were out this weekend at the very romantic and luxurious Bacara Resort & Spa in Santa Barbara, CA with son Knight."
Nas says he and his ex are becoming friends -- following a nuclear divorce -- for the sake of their 3-year-old son. Our luxurious spies tell us... Nas and Kelis were having lots of fun ... getting along great ... BUT nothing seemed romantic. Good for them.
