So Sydney Liebes is the lucky gal who is the new object of Robert Pattinson's affection! And seeing as she's a personal trainer who is spending nearly every day with the 27-year-old star, it makes sense that they're workout buddies -- and then some!

On Monday Rob and Sydney hit the gym together, and after that the two took off in his car. Sydney is helping whip the Twilight hunk in shape for his upcoming film Mission Blacklist, and a friend of Sydney's tells X17online exclusively:

"I talked to Sydney and she's excited about training Rob. She said, 'He's a really cool guy; we're spending a lot of time together in the gym almost every day. He's fun to work with.'"

So just who is the perky brunette? She's from Westlake Village, and she graduated from high school in 2008, so she's definitely on the younger side. And get this -- though she works at A-list trainer Harley Pasternak's private gym, she's very new to the fitness industry. The pal tells X17online exclusively:

"Sydney just started working as a trainer this summer, so I'm surprised she got this gig. I don't know why Rob would hire her, when she has so little experience, other than because she's cute."

Maybe these pics had something to do with it? It looks like Sydney has dabbled a bit in modeling:

Looks like the rumors are true! And now that her ex-fiance Liam Hemsworth has been snapped sucking face with his new lady love Eiza Gonzalez, Miley Cyrus is certainly allowed to get back in the dating game!

Miley's producer/new beau Mike WiLL Made It picked the 20-year-old singer up from her Toluca Lake home on Tuesday evening, and after that the duo went to a pal's house, where they stayed until about midnight. Then Miley and her new man went to Bootsy Bellows and she made every effort not to be seen.

A photographer on the scene tells X17online:

"Miley ducked in the back seat of the car and she clearly didn't want to be photographed with Mike, but they were obviously on a date."

But here's what we wanna know ... Is this a recent fling or was Miley's romance with Mike something that strained her relationship with Liam? After all, Miles has been in the recording studio with Mike all summer, and she made her final red carpet appearance with Liam just last month...

We asked Mike if HE'S responsible for breaking up Miley and Liam and here's what he said ...

He's a trooper!

Justin Timberlake treated fans to a mini concert last night on Hollywood Blvd. despite being under the weather, and the Grammy winner made sure to play all the hits for the massive crowd that gathered to watch him perform.

The show was for a Jimmy Kimmel Live! outdoor concert series, and the chart topper belted out some of his best songs like "Mirrors" and "Take Back The Night" in an effort to promote the second part of his album The 20/20 Experience.

JT looks like a lumberjack bringing sexy back in that outfit!

On Tuesday evening Jessica Simpson went to dinner with beau Eric Johnson and their adorable daughter Maxwell at Sagebrush in Calabasas, and the proud parents may have left their three-month-old son Ace at home, but Jess definitely busted out the twins:



"With two kids, we have our hands full, but every day is a new adventure," Jess told Us Weekly last month when she showed off the first photos of Ace in the glossy. "It's fun! I feel very at peace with being a mom."

It looks like she's also had plenty of time to hit the gym -- she's definitely well on her way to getting her pre-baby body back!

Hilary Duff smiled on her way to visit a friend in the valley on Tuesday, and we always say this, but we're just DYING to raid her closet! From the bright skinnies to the ankle boots, the former Disney star certainly loves to get her shop on.

While the Duffster made a few guest appearances on TV shows over the summer (Two and a Half Men and Raising Hope), she's getting back to her pop star roots and getting back in the studio. Yesterday she tweeted a photo of herself recording a new track, and last month when asked about her next EP during a Twitter Q&A she told fans, "I'm exploring a lot of cool options & don't want to give a timeline yet but I promise exciting stuff is coming.. I'm super into EDM. Definitely catchy hooks I've always cared a lot abt lyrics & love to dance!"

Can't wait to hear it!

Denise Richards paid a visit to the hair salon on Tuesday afternoon, and the 42-year-old actress flashed us a smile on the way in. She wowed us back in the late 90s when she was a Bond girl, and even though she's not wearing a skimpy outfit here, she still looks fantastic!

Denise dropped her kids off at school, and then she headed to the set of Hot in Cleveland to work for a few hours. Denise will resume production on Twisted next month, so she's definitely staying busy.

In other news, Charlie Sheen recently purchased a mansion in Mulholland Estates for his ex-wife Brooke Mueller, so when she finally gets out of rehab, she'll practically be Denise's next door neighbor. Mueller had previously moved in to a Tarzana estate that once belonged to Melanie Brown, but she reportedly threw a hissy fit when she found out Charlie bought a pad for his other ex-wifey in a more desirable part of town.

"Brooke insisted that Charlie buy her a house in Mulholland Estates too,” an insider told Radar. “She said it wasn’t fair that Denise got a house and she didn’t.” We're not even going to get in to that...

Lamar Odom's estranged father Joe boldly proclaimed that his son would be "better off" without the Kardashian family, and though Lamar has been laying low, he took to his twitter today to slam his father for his remarks.

The NBA star wrote:

"Won't continue 2 speak on this but I have got 2 let this out real quick. I have let this man and many others get away with a lot of sh*t. He wasn't there 2 raise me. He was absent ALL of my life due to his own demons. My mother and grandmother raised me. Queens raised me. For the first time since they left, came a blessing of a FAMILY that I married into. FAMILY. That man wasn't even invited to my wedding. He has never met my mother in law and some of my other family. How can a man who has NOT once called me to check on my well being have the nerve to talk so recklessly about his own "son". He is my downfall! His own demons may be the ONLY thing he gave 2 me.

He disrespecting the ONLY FAMILY that has loved me without expecting anything in return. They are the ONLY ones that have been here consistently 4 me during this dark time. Only person 2 blame is myself. Say what you want about me but leave the ones who have done nothing but protect and love me out of this! This goes to out to everyone!

So what caused all this? Earlier this week Joe told Radar, "They brought him down. Let him go and get his life together. I think the best thing for him would be to have a clean break, divorce Khloe and as a single man try and get his life back together."

After reports of his alleged infidelity and drug use surfaced this summer, Odom was arrested last month for D.U.I., and just days before his arrest, his teammates and agent attempted to have an intervention, but he reportedly left and didn't want their help. Though Lamar has spent some time with Khloe since those incidents occurred, we haven't seen or heard about them being together. Then again, she did wear her wedding ring on Monday night for dinner with the family...

Is Yeezy decorating his home or getting inspiration for a new music video?

On Tuesday afternoon Kanye West stopped by Vision Scenery, which is a full service set construction company that provides "custom sets, props, models, miniatures, and rentals for commercials, music videos, film, television, exhibits, displays and still shoots." Kanye definitely has a tendency to go cray crazy when it comes to his video projects, but given that he and baby mama Kim Kardashian have gold-plated toilets in their new Bel-Air home, we couldn't be surprised if he's putting together something for their love nest! And seeing as he has an unlimited budget, we're guessing the company would be willing to work with the rapper on a more personal project.

And is it just us, or has the self-proclaimed "number one rock star on the planet" put on a few pounds? Maybe he gained a little bit of weight so Kim wouldn't feel bad about the 60 pounds she gained during her pregnancy?
