The former hip-hop supercouple has been embroiled in a bitter divorce since April. In July, Nas was ordered to pay the “Milkshake” hitmaker $55,000-a-week in spousal and child support by a New York judge, but now the star is trying to knock down those payments.

Nas is also seeking joint custody of his baby son.

The IRS has requested that the rapper pay the massive figure for outstanding taxes owed between 2006 and 2007, according to TMZ.com.

The tax bill is the least in a string of money troubles for Nas, who was recently ordered to pay his estranged wife Kelis and their infant son Knight $30,471 a month in support.

A heartbreaking three minute video shot by a fellow student on her cell phone was released to police and ultimately provided the evidence which led to the arrests and charges of four teenagers — Silvonus Shannon, 19, Eric Carson, 16, Eugene Bailey, 18, and Eugene Riley, 18.

Nas writes:
Dear Young Warriors fighting the wrong wars!
Killing each other is definitely played out. Being hurt from the lost of a love one was never cool. Dear Young Warriors fighting the wrong war! I know that feeling , that frustration with life and needing to take it out on someone, any one. But….

When we see each other why do we see hatred? Why were we born in a storm, born soldiers, WARRIORS….and instead of building each other up we are at war with each other.. May the soul of this young person find peace with the almighty. I’m with you young warriors. You’re me and I’m you. But trust me! you are fighting the wrong war.
-Nas

Kelis filed for divorce in April, citing irreconcilable differences amid rumors of verbal abuse and alleged infidelity. The “Milkshake” star was pregnant with the couples first child at the time — a son named Knight, who is now two months old. Nonetheless, the hip-hop twosome has fueled rumours of a reunion after they attended a party together at New York City’s Marquee on Monday and were seen kissing inside.

A source said: “Nas and Kelis were celebrating his birthday with some friends and you couldn’t tell they were divorcing to look at them. They seemed very intimate and were kissing and hugging and even left together.”

Shortly after Knight’s birth, a court ordered Nas to pay his estranged spouse $30,471 spousal support a month, and also provide his son with $9,027. He was also ordered to pay $45,000 for Kelis’ legal fees and for a forensic accountant.

The couple married in Atlanta in 2005.

In an interview with the Straight Magazine to promote his show in Canada last weekend, Nas briefly addressed the rumors flooding the interwebs about his relationship with soon-to-be-ex-wife Kelis. Despite reports that he was unfaithful, and is even expecting a child outside of his marriage, Nas believes he was a “hell of a husband.”

“It’s funny that someone would even care about some Nasir Jones shit,” he told the magazine. “I’m still that kid from the block at the end of the day.… So when I watch this shit, it’s surreal. We get a good laugh off it and say, ‘Hey, they’re talking about me again and it’s some funny shit.’…I heard that I was a cheater….It almost sounds like I was a bad husband. Not to say I was the greatest — I’m not perfect in anything I do — but I think I deserve a fucking trophy. If I do say so myself, without sounding too cocky, I gotta say I was a hell of a husband and a hell of a dad…..It’s unfortunate when business is out there about your personal shit, especially when you’re really not the guy to be having his shit out there. The sad thing is, you’ve got to get used to it. My skin is so thick that I probably need to write a book for people who are not ready for anything crazy.”

Wow — Kelis wasn’t joking when she went on the Twitter tangent against cheaters earlier this summer.

According to a scoop featured in Wednesday’s edition of The Chicago Sun-Times, on top of having to shell out approximately $44,000 a month to his “Milshakin’” ex for spousal and child support for their newborn son Knight — there’s now word that one of Nas’ Buss It Babies is currently pregnant with another of “God Son’s” seeds …

Los Angeles Superior Court Judge Louis Meisinger issued the order during a Thursday afternoon hearing.

In April, Kelis, whose full name is Kelis Rogers, filed for divorce from the rapper after four years of marriage. The two have spent the past several months arguing over support payments.

The hip-hop star had been performing in New York earlier in the night, where he announced to fans in the crowd that he was drunk on champagne, according to the gossip site. Nas later turned up at the bedside of his estranged wife — R&B singer Kelis –but staff turned him away, reportedly because he was under the influence of alcohol.

A statement issued by Kelis’ publicist early Thursday seems to support at least the claims that the new father was no where to be found when Kelis’ “Milkshake” brought a baby boy to the yard.

“Kelis gave birth to Knight Jones last night on July 22nd around 9PM. Weighing a healthy 7.8lbs, the beautiful baby boy and his mother are doing wonderful. This was a natural birth and Kelis had been in labor since early Monday morning around 2AM. Knight was delivered in a NYC hospital with her mother and sister in the room.”

Kelis is already Tweeting on the birth of her new son:

Ok so I did it, he’s 7.8 pounds of the greatest stuff on earth…I was in labor for 3 of the longest most painful days of my life. I don’t understand when women say they don’t remember giving birth…I will remember for the rest of my life. He’s kinda perfect btw.
