The VERY last song Whitney Houston ever recorded has finally been released ... a duet with Jordin Sparks ... which Whitney performed just 4 days before her death.

The song is called "Celebrate" -- from her upcoming movie "Sparkle" in which she plays Jordin's mother.

After Whitney died, officials found evidence of hardcore drug use in her hotel room and in her system ... but producer Harvey Mason Jr. didn't seem to think her addiction had an affect on the quality of her performance.

Mason Jr. told People.com, Houston was "really positive" during the recording ... saying, "We ended the session dancing around the control room while she said 'Turn it up! Turn it up!' She was so fun-loving."

The movie is scheduled to be released in August.

Whitney Houston's final movie is on lockdown ... over fears that people will leak Whitney's scenes and music ... TMZ has learned.

Sources connected to the production tell us ... the people working on "Sparkle" -- starring Whitney and Jordin Sparks -- are working "around the clock" to finish post-production work on the movie as quickly as possible.

We're told the building where the film is being edited is also under tight watch -- with ramped up security in the hopes of preemptively clogging a leak.

So far, no comment from Sony.

Some examples of sibling love in Hollywood:



1) Jordin Sparks' brother getting a tattoo to show his love for his sis.
2) That time Angelina Jolie made out with her brother.

These are the only two examples.

P.S. According to King James, 1 Timothy 4:12 does not say, "I am creeped out by my bro's tat."

Russell Brand be damned! America's favorite Evangelical Christian dandy boy band virgins, the Jonas Brothers, showed off their sexual abstinence bling in London on Wednesday.

Their bodyguard, Jordin Sparks, was nowhere in sight.

The Jonas Brothers all wear purity rings -- but VMA host Russell Brand got in some serious hot water with his extremely impure jokes about the Disney virgins.

Humorless "Idol" champ Jordin Sparks ('memba her!?) defended the boys after Brand bragged he'd bag 'em all by the end of the night. Hope he stayed away from Nick -- that kid's only 15!

Whether you really choose to listen to her or not, one thing's for sure: Jordin Sparks' singing career is not over. Not even close.

The alarm was sounded when Jordin had to ditch gigs this weekend because of what was described as a scary-sounding "acute vocal chord hemorrhage," which led to speculation that her career might be ovah! Sparks' rep tells us that while Jordin's condition is in fact "serious," it's manageable and she'll be back on tour in May. All her dates through the end of April have been scrapped.

The main thing is, we're told, that young Jordin needs to learn that vocal rest is vocal rest! Bettah keep that trap shut -- or else she'll be opening housing developments!

\Blake Lewis is one tatted-up fool -- but would he really get inked down there?


TMZ was with the "American Idol" runner-up as he went to Dr. TATTOFF to get some ink on his back faded out -- to make room for a new, larger tattoo. Blake joked about what tats he'd get on his junk -- and came up with some interesting ideas.

What was K-Fed doing while Britney was fighting for supervised visitation with their Sean and Jayden? Why, filming yet another episode of "One Tree Hill," of course. Daddy's got some bills to pay!

After filming wrapped, Kev and crew toddled over to a local bar for a night of heavy partying, reports People. At one point, the DJ played Brit-Brit's new jam, "Gimme More," but Federline failed to bat an eyelash. "He didn't have a reaction. He wasn't dancing," said one clubgoer.

American Idol's Underage Drama

Traveling with the "American Idol" tour isn't just child's play -- and the U.S. Department of Labor can prove it. This past week, 19 Touring, the parent company of "American Idols Live Tour '07," was fined $5,000 for violating child labor laws. The reason? Underage performers Jordin Sparks and Sanjaya Malakar.

The Labor Department also says that 19 Touring lacked a certificate of eligibility to employ singers under the age of 18. Who says Sanjaya's a singer?

The company eventually filed the proper paperwork but will still have to pay a fine.

Rosie: I Made J.Lo

Jennifer Lopez was just Jenny from the block -- fat and clumsy Jenny from the block, when she got her start, says squeaky-voiced Rosie Perez in the new issue of Out magazine. Rosie says it was she, not Keenan Ivory Wayans, who hired Lopez as a dancer on the hit '90s comedy show "In Living Color." "He didn't want her because she was overweight and didn't dance well, but I said, 'she has star quality.'"

Party Favors..."Dirty Sexy Money" Star Has Issues...

Samaire Armstrong, who plays a blonde rich beeyotch on "Dirty Sexy Money" entered an outpatient facility to deal with "personal issues," according to People. A rep for Armstrong says that she'll continue to work on the show and will be "completing her treatment" in a matter of weeks.

TMZ spies infiltrated the L.A. stop of the "American Idol" tour at Staples Center on Monday, and snapped candid pics of all the Season 6 wannabeens. This was their now!

Unlike last year's "Idol" tour, this time, all ten contestants -- even winner Jordin Sparks -- happily stopped by to meet and greet their fans. No Daughtry divas this season!

From Sanjaya to Blake, check out the karaoke superstars in all their fanatical glory -- for the last time!

Things are starting to really heat up on the "American Idol" concert tour -- backstage!

TMZ has learned that "Idol" winner Jordin Sparks has fallen head ovah heels for Justin Timberfake wannabeen Chris Richardson! This is her now! While she and runner-up Blake Lewis are just friends, we're told Jordin has a huge crush on 23-year-old Richardson -- despite his penchant for late nights and hanging out with the likes of Lauren Conrad. Boys will be dogs!

Sources on the tour tell us that because Jordin is only 17, her minders and family members are doing everything they can to keep from letting anything -- or anyone! -- get in the way of the underage star's bright future. Sexy and 17 -- and off limits!

They've denied up and down that they're an item, but Jordin Sparks and Blake Lewis have been looking awfully co-co-co-zy in the afterglow of their "American Idol" glory.

A TMZ spy spotted the "Idol" finalists "holding hands" while shopping at a Fry's Electronics store near L.A. We're told that they wandered around the store, unmolested, and seemed "happy" together. Blake was overheard saying to the 17-year-old Jordin, "We should call your mom." Need a ride, kids?

Here, B & J yuk it up for photogs, as Blake rocks an outfit that seamlessly blends New Kids on The Block and low-rent surf dude chic.

The pair will tour with the rest of the "Idol" crew this summer, but it looks like they've got their own duet.
