If Britney gets a little color while she's there, you'll be able to kiss her tan southern Louisiana a**!

Josh Duhamel You Can't Keep a Good Man Down

Before Josh Duhamel had a run-in with a flight attendant on a plane ... he had a run-in with a car on the streets of NYC.

As TMZ first reported, Duhamel was escorted off of a flight from NY to KY after he refused to turn off his BlackBerry.

The pics (above) were taken after Josh left FAO Schwarz with Fergie, but hours before he went to the airport. The slip was totally innocent -- Josh and Fergie were being following by paparazzi as they got in their car to leave the famous toy store.

Boom boom pow.

Xtina's New Man -- It's Getting Personal

Christina Aguilera's new arm candy, Matthew Rutler, is skipping his band's gig this weekend ... yet showed up at LAX today with the blonde bombshell. Did he find a higher paying gig?

The Nate Mott Band posted on it's Facebook page on Wednesday: "Do (sic) to personal reasons Matthew Rutler our guitarist will not be ableto perform at Twin Rivers Casino Friday Night."

Best "personal reason" ever.

Justin Bieber -- Now With Mustache

Sick of the pre-pubescent peach fuzz facial hair, 16-year-old Justin Bieber decided to give himself a mustache last night ... with the help of some black ink.

Fake it 'til you make it.

Uma & Quentin Downing Booze from Her Shoes

Quentin Tarantino got a little taste of heaven last night -- when the foot-obsessed director was allowed to drink champagne out of the Holy Grail of foot-fetish receptacles ... Uma Thurman's stiletto.

It all went down the hatch at Quentin's Friar's Club Roast in New York City -- where Uma made Quentin's dreams come true by pouring them two shoefuls of the bubbly stuff.

From the look of things ... one of them knocked it back with a bit more vigor than the other.

Toe-riffic.

LeBron Parties 'til 2AM ... then Crushes Pistons

Before the Miami Heat destroyed the Detroit Pistons last night, LeBron James got into the zone ... by partying with some teammates into the early hours on Wednesday morning.

Just hours before the Pistons game, LeBron was spotted leaving Miami's Lucky Strike bowling alley around 2 AM in a douche bag Orange Jeep.

'Bron spent the night hanging out with embattled boxer Floyd Mayweather.

Maybe he needed to pick up some tips before his super-highly anticipated return to Cleveland tonight ... where he's set to square off with the Cavs ... and thousands of angry fans.

Tony Parker & Eva Longoria -- Table for Two Exes

Tony Parker and Eva Longoria reunited for a lunch date in L.A. on Wednesday -- two weeks after she filed to divorce him in Cali ... which was followed by Tony's own filing in Texas. Awwwwkward.

They met on neutral ground ... at a hotel in the L.A. area. Tony was in town because his San Antonio Spurs played the Clippers last night -- but based on Eva's gestures and Tony's expressions ... we're guessing there was little hoops strategy discussed.

No lawyers were present to split the bill.

Joe Jackson's Brazilian Babe Tour

When not compromising his wrongful death lawsuit against Dr. Conrad Murray in Brazil this week, Joe Jackson has been throwing back drinks and hangin' with pretty young things.

While Papa Joe is technically in South America on a book tour, he's spending more time promoting his smooth moves.

No word if Michael would have supported his mac daddy in these instances too.

Hose.

T-Pain was nowhere in sight.

Britney Spears -- Me Against the Fries

While visiting family in Louisiana, Britney Spears decided to feast on the local cuisine ... by devouring some french fries from Sonic.

Why yes, she would like fries with that!

Kate Plus Tanning

Kate Gosselin was thankful for a little alone time today, hitting up a tanning salon and then a FedEx near her home in Reading, PA.

Tantastic.

Brooke Mueller Thanksgiving at a Sober House

Brooke Mueller -- Charlie Sheen's soon-to-be ex -- had quite the Thanksgiving, spending the night before in an L.A. hotel room and moving the party to a sober living facility ... sources tell TMZ.

Mueller was spotted yesterday (above) leaving the Farmer's Daughter Hotel -- located near the famous Farmer's Market in Los Angeles -- at around 10:00 AM on Thanksgiving morning. As you can see from the photo, Mueller looks like she had quite the evening.

The photographer tells TMZ Mueller was escorted straight from the hotel to a sober living facility in Beverly Hills.

Mueller has been in and out of rehab in the last few years.

TMZ made multiple attempts to contact Mueller. We never heard back.

UPDATE: After a day and a half, Mueller's rep finally got back to us with this version of events -- Brooke was shooting scenes in the hotel for her reality show. The rep acknowledges that Brooke left the hotel and went directly to the sober house where she has been receiving treatment. The rep did not say why it was necessary for a disheveled Brooke to be escorted by a representative of the sober house on Thanksgiving morning to the treatment facility. And the rep adds ... Brooke's parents were talking care of her kids.

Miley and Her Mom -- Nothin' but a Good Time

Miley Cyrus and her mother Tish spent a little mother/adult daughter time yesterday by hitting a nail salon and then going out to lunch.

In a completed unrelated story that has nothing to do with anything ... Bret Michaels performed in Atlantic City last night.
