Gwen Stefani and her son Kingston arrived at JFK Airport on Tuesday, and the two sported some very interesting hairstyles when we snapped them walking down the tarmac! Gwen wore her blonde locks in a spiky ponytail, and Kingston appears to have dyed his hair a lovely shade of teal-y green.

But is the 6-year-old too young to be dyeing his hair? Or maybe it's just a temporary comb in gel?

Katherine Jackson is currently on her way back home to Calabasas from her vacation with family in Arizona.

The 82-year-old Jackson matriarch is aware of TJ Jackson's (Tito's son) move to take over as temporary guardian of Michael's three kids ... Paris, Prince and Blanket.

We've learned Katherine Jackson spoke to TJ last night.

Our Jackson family source tells us that TJ asked Katherine if he could take over as legal guardian. We've learned exclusively that Mrs. Jackson told TJ specifically:

"I don't give you authority to become temporary guardian of the children. It's not going to happen. I'm coming home tomorrow."

Of course "tomorrow" is now today. Our source adds:

"This is a conspiracy to take the children from Katherine Jackson. The executors, John McClain and John Branca, are instructing TJ what to do."

John Branca, co-executor of Michael's estate, has released the following statement:

"We are concerned that we do what we can to protect them from undue influences, bullying, greed, and other unfortunate circumstances."

Katherine is currently en route from Arizona to Calabasas.

ABC News will soon be releasing video of Katherine.

X17online exclusively has learned that Katherine Jackson spoke with Paris, Prince and Blanket Jackson last night ... telling Michael's three children that she'd be returning to their Calabasas home today.

Our Jackson family source tells us:

"Katherine was beyond thrilled to speak with the three kids. The kids were excited to know she's coming home today, especially Paris."

We're told Katherine is very much aware of what's been going on over the last week at her home, and she's "infuriated" over the situation.

The 82-year-old Jackson matriarch will be making changes to her staffing upon her return. X17 first told you that "Paris has confided in her cousins that Trent and a security member have been "putting her up to Tweeting out messages against the family."

X17online obtained the exclusive photo of Katherine visiting her daughter Rebbie in Arizona and enjoying the card game, Uno. Arizona Sheriff's authorities have confirmed that the Jackson matriarch is "having a good time with family."

No one can deny ... LeAnn Rimes and her hubby Eddie Cibrian KNOW how to take a sexy picture.

The couple, married just over a year now, posed for a sultry pic in support of the NOH8 Campaign. The campaign is a silent protest photo project against California Proposition 8.

Rimes, who is a big supporter of gay rights, recently performed two sold out shows with the Gay Men's Chorus of Los Angeles.

Check out video below of the country songstress singing "What I Cannot Change." Incredible!

Selena Gomez must really be digging the exposed-bra look, because this is the second day in a row the former Disney star has rocked the racy style!

Gomez looked grunge-chic in an oversized black tank that let her baby blue bra peek out of the sides, paired with skinny jeans, tan ankle boots and a pretty patterned scarf as she picked up an herbal refreshment with a few pals, on Tuesday afternoon, and she even stopped to pose for a pic with a young fan!

The singer/actress celebrated her 20th birthday last Sunday with a big win at the Teen Choice Awards, and a romantic date with beau Justin Bieber at Il Cielo restaurant in Beverly Hills.

After the bday festivities, Selena shared via Twitter: "Beyond blessed, so much love. Thank you for the most incredible birthday yet! I'm truly, truly grateful. I love my family, friends and all of you."

It's not hard to see why the ladies love Simon Cowell!

The music mogul became an instant chick magnet after he touched down in Miami to hold auditions for the second season of The X-Factor early this week, and he definitely seemed to be enjoying it!

Cowell is in town with new judges Britney Spears and Demi Lovato, and he recently told X17 of the divalicious duo: “She [Spears]’s a really, really good judge. Demi is a brat. But there’s something really likeable about her as well. That’s what they both bring and it works brilliantly.”

In other news, it was recently announced that Mariah Carey has signed on as the newest American Idol judge, and it sounds like the Grammy winner might be the next Paula Abdul. "I think she’s going to find it difficult to say no. You’ve got to say no to people. She’s sweet but I think she’ll be great. I got wind of this last week so I knew it was going to happen,” Simon recently revealed.

X-Factor returns to Fox on September 12.

She's come a long way since "Jenny from the Block!"

Jennifer Lopez looked ravishing in a sexy red dress and suede Christian Louboutin Bis Un Bout pumps, as she arrived to her surprise 43rd birthday party on beau Casper Smart's arm aboard a private yacht in NYC, on Tuesday evening.

The day before her lavish party, Smart was seen picking out items at a racy adult's only shop in The Big Apple, so there's no doubt the former American Idol judge received a pleasurable surprise this year!

After the festivities, La Lopez indulged in a sweet birthday treat, sharing via Twitter: "Mr.Softee vanilla cone w/sprinkles on my birthday!! #itsaNewYorkthing #happygirl. Somebody loves me...:)"

Happy birthday J. Lo!

Bad news, Twihards!

Despite the fact that Kristen Stewart and Robert Pattinson have been in an exclusive relationship for the past three years, the actress recently hooked up with her Snow White and the Huntsman director, and married father of two, Rupert Sanders, according to reports.

A source tells People mag:

"Kristen is absolutely devastated. It was a mistake and a complete lapse in judgment. She wasn't having an affair with Rupert. It was just a fleeting moment that shouldn't have happened. She never meant to hurt anyone. She's a good person who just made a bad choice."

The Twilight stars were photographed just days ago looking lovey-dovey at Comic-Con, and the 26-year-old actor recently confessed to BlackBook: "It is true that Kristen has always done something to me that others haven’t."

A rep for Stewart had no comment, while Sanders' rep could not be reached, but it seemed the director only had eyes for his star at the Huntsman premiere in May!
