For most people ... a $1.1 million debt to the IRS is a REALLY BIG DEAL ... but when you're Lionel Richie and worth an estimated $200 mil ... it's probably just a nuisance.

According to documents obtained by TMZ ... Richie owes the federal government $1,130,609.11 in unpaid income tax for 2010.

The singer has been slapped with a lien ... which means Uncle Sam can start going after his stuff if he doesn't fork over the dough ASAP.

We called Lionel's rep for comment -- still waiting for a call back.

Currently having the #2 album in the country isn't the only reason Lionel Richie should be dancing on the ceiling.

Here's the 36-year-old Best Song Oscar winner back in 1986 (left) -- and 26 years later, the 62-year-old at his concert in Vegas this week (right).

Hello.

Darius Rucker's new duet with Lionel Richie got one TMZer up and dancing (kinda sorta) ... but even bigger -- the bombshell DR dropped about some classic Hootie history!

Lionel Richie returned home last night to find his street barricaded off by the Bev Hills PD -- someone went thievin' in his neighborhood?!

Though his home was spared, cops responded to an armed robbery on another house a few doors down. The suspect is still on the loose. The hold-up occurred around 10:30pm, Lionel returned home around 2:30am -- party all the night long!

So you're a 58-year-old grandpa on the prowl for hot chicks at 4:00 AM. You're about to seal the deal in the Aston Martin. And then TMZ jock blocks your plan by asking about grandfather-dom.

TMZ and a herd of photogs spotted a baby-totin' Isla Fisher yesterday as she left the Mercer Hotel in Soho. A stalker chased Isla while trying to pass off his CD -- and blocked paps from getting a shot -- Isla wasn't havin' any of it. Nearby, Gabriel Byrne walked by Da Silvano -- not giving anything up.


In L.A.: Janet Jackson and Jermaine Dupri arriving separately at S Bar, then leaving together. Kate Hudson finishing a fish dinner at Nobu in Malibu. Jerry Stiller faced photogs at Chateau Marmont, and Lionel Richie drove his lady in a Beemer.

They're allegedly broken up (who knew they were even dating?!) but Miley Cyrus and Nick Jonas of the Jonas Brothers are still staying at the same hotel. Probably not any underage hanky-panky here though -- they're also on tour together.


Also out over the weekend -- an overly cheery Martin Sheen, New Years resolution-less Kevin Connolly and Lionel Richie, who made it across the exclusive doors of Villa. In Miami: sexy Sophia Bush and Kim-less Kardashian sisters.

All this and more in today's "Goodbye 2007" edition of Star Catcher.

His daughter is having a baby, but not even Lionel Richie knows the sex of Nicole's spawn yet, keeping photogs dancing in the dark when TMZ asked what color cigars he'll be buying.

Cameras also caught Destiny's Child Kelly Rowland in Malibu, where she promised to watch TMZ on TV ... as long as we're nice to her and her friends! Also in Malibu -- Sir Anthony Hopkins, who wasn't responsive when our cameraman made a lame "Silence of the Lambs" joke. Sorry, Sir.

Also out in L.A.: Eddie Kaye Thomas, who had a defeated look when asked what projects he has coming up, and Caroline D'Amore, who had some nutrition advice for paps.

In New York: Larry David had a run-in with chef Wolfgang Puck, later meeting up with Jeff Garlin and Rich Eisen. 70-year-old Dustin Hoffman knocked the cameraman for not knowing he lived in the Big Apple, while celebufriend Gayle King wished she had worn more makeup.

David Hasselhoff let his chest hair run wild and free out front of Hyde. And that's not all..

Last night Hollywood was out in full force -- "Fantastic" force -- for Chris Evans' birthday party. The "Fantastic Four: Rise of the Silver Surfer" star's party was attended by co-star Michael Chiklis, and pals Adam Brody and J.C. Chasez.

Lionel Richie said the jury was still out on Nicole's pregnancy. When asked whether or not he'd be babysitting, he responded, "maybe, I don't know.'

Andy Milonakis was spotted out front of Les Deux, where he very generously handed a homeless man a dollar bill, and advised no one in particular to "tell all the little Hollywood d-bags in training to keep it real." Takes one to know one.

Patrick Swayze was out in front of the Prince concert followed by his long-haired doppel-Swayze.

Pop-punk band New Found Glory and adult contemporary icon Lionel Richie may not have much in common musically, but they obviously share a likeness in album titles.

On Tuesday, Lionel's latest album, "Coming Home", was released. New Found Glory's new CD hits stores on September 19, and just so happens to also be called "Coming Home."

Coincidence? Perhaps. But New Found Glory has reached out to Richie by issuing an "open letter to Nicole's Dad" to celebrate their "pure genius" fluke.

The tongue-in-cheek press release also states that while it may be too late for Lionel to change the album's title, they "expect a call before your next album comes out." If not, New Found Glory says they may have to name their next CD "Dancing on the Ceiling" and have it feature "original punk rock songs as 'Say You, Say Me' & 'All Night Long.'" Which, for you non-Lionel Richie fans out there, are the titles of some of Lionel's biggest hits from the 80s.

While there's no way to tell which artist came up with the title first, perhaps the young'uns in New Found Glory should check out the oldies section at Blockbuster and pick up a copy of the 1978 Oscar-winning film starring Jane Fonda which, what do you know, is also called "Coming Home." Hello!
