Looks like X Factor executives have finally nailed down two hosts ... Khloe Kardashian and Mario Lopez.

The twosome have been tight-lipped about their new gigs, but each are expected to rake in at least $1 million for the season.

And in a non-coincidental type of way last night, Mario Lopez was seen introducing Green Day alongside X Factor's Demi Lovato at the iHeartRadio Music Festival.

Since Simon Cowell agreed to Britney Spears' $15 million deal, we have a feeling Khloe and Mario's salary seems like chump change.

The two hosts will make their debut next month.

And the girls were even joined by mom Gina too!

Vanessa Hudgens and her little sister Stella were snapped leaving the gym in Los Angeles yesterday, and after that the 23-year-old starlet headed to Whole Foods for some groceries. After reportedly gaining 15 pounds for her role in last year's Gimme Shelter, V. Hudge has been busting her booty trying to drop the extra weight. Glad to see she's going about it the healthy way!

Over the weekend Vanessa and her lil sis went to Halloween Horror Nights at Universal Studios, and she posted this adorable pic of the two of them:

Miley Cyrus is one lucky lady!

Liam Hemsworth and a pal were snapped hitting the gym on Monday afternoon, and the 22-year-old showed off his buff biceps and sexy pecs in a tight white tank top.

Despite rumors that Miley and Liam's relationship is on the rocks, it sounds like everything is fine in the bedroom! Someone at the National Enquirer overheard Miley and a pal gabbing at lunch, and apparently she couldn't stop bragging about her sex life! "There's no holds barred," Miley allegedly gushed to her friend. "The sex is wild! Liam fulfills all my fantasies, and I fulfill his."

Miley reportedly admitted that the two "do it everywhere - it's become a game to see who can come up with the most bizarre place!" Hopefully they're not thinking of doing it anywhere where there might be cameras...

Britney Spears has definitely had a big influence on her niece Maddie.

The little 4-year-old cutie, whose mom is Brit's younger sis Jamie Lynn, is striking a pose ... dressed as Brit from her "Baby One More Time" music video. Lil' Maddie was in costume for "celebrity day" at her Catholic school.

Brit was only 16 when the video debuted on MTV in 1998. Time has definitely flown by!

Bar Refaeli's Sex Tape Kickstarter from Bar Refaeli

Looks like Leonardo DiCaprio's ex wants us to think she's got a sense of humor, but we're not exactly sure what she's accomplished here...

The Israeli model appears in Funny or Die's latest video, which is set up to look like a Kickstarter campaign to raise funding for her sex tape. Click the video above to see Bar's comedic acting skills!

LeAnn Rimes is opening up about the benefits of treatment.

The 30-year-old country songstress told the Boston Herald:

"It's hard to take it day after day of reading and seeing things that someone you don't even know says about you. As much as you said you don't want it to penetrate, it does, because you're human."

As for her recent treatment:

"I've been in therapy my whole life. I like going. I like being able to have that third-party input and someone to listen that has nothing to do with your life. Everyone has an opinion of how I am and how I should be, and now I'm focusing on how I want to be."

Rimes' upcoming album Spitfire hits stores next Spring.

But that's not a belly -- those are the abs of a girl who obviously busts her booty at the gym! Or at least one who is genetically blessed...

After rocking a pair of sexy thigh high boots earlier in the evening, Rihanna slipped into something a bit more comfortable when we snapped her out and about in New York City on Monday night.

And speaking of sexy, the 24-year-old R&B superstar will perform her new hit single "Diamonds" at the Victoria's Secret Fashion Show, which will air on December 4, 2012. "Diamonds" is currently number one in 26 countries ... not to shabby!

Robert Pattinson attended The Black Keys' show at the Sayers Club in Hollywood last night, and while no one snapped photos of the Twilight hunk arriving or leaving the popular venue, he did pose for a Twitpic with 98.7 DJ Kennedy!

Rob arrived with a group of pals, and he was "definitely enjoying the music, getting more into it as the set went on," an eyewitness tells Us Weekly. "He cheered and clapped at the end of each song." K. Stew's main squeeze puffed on an electronic cigarette, and sources at the club say he "sipped on beer and mixed drinks throughout the evening ... He was clearly enjoying the music and in a good mood. In between songs he would make comments or joke around with his friends."

We're glad to see him in a better mood, and we have a feeling this has everything to do with him reconciling with Kristen Stewart. Can't wait to see them side by side on the red carpet at the Breaking Dawn premiere on October 28!
