Miley Cyrus posted some photos of herself with two different wigs last night, and we're not sure what she's going to be for Halloween, but this really makes us miss her long hair! The singer, who turns 21 next month, tweeted the above shot and wrote, "Wigzzzzzz" and "Wigzzzzzz part 2."

Miley famously lopped off her long locks and bleached them blonde over a year ago, and at the time she said we would never see her with long hair again, but just 6 months later she admitted that it was a rash decision. Miles told bestie Kelly Osbourne on E!'s Fashion Police, "I'm secretly tugging on it every night and taking Viviscal [a hair growth supplement]. I'm not going to lie. But I'm going to rock it while I have it."

Way to pull a Khloe Kardashian and keep us guessing!

On Tuesday Alessandra Ambrosio lunched at Joan's on Third with a friend, and yet again, the 32-year-old model left her engagement ring at home. Despite rumors that Ale and fiance Jamie Mazur are going through a trial separation, her rep denied the reports and said in a statement, "It's not true, they are still happily together."

However, prior to that a source told Life & Style, "They're still on friendly terms because of the kids and spend time together, but for now, they are separated and there will be no wedding ... They definitely have a roller coaster of a relationship.”

Hmm, what to believe?

A pregnant Gwen Stefani and hubby Gavin Rossdale went to a checkup on Tuesday at the doctor's office, and the couple were all smiles when X17 photographers snapped them leaving. Gwen has yet to officially confirm that she's expecting (or whether she's having a boy or a girl), but we've seen her baby bump for about a month now, so it seems pretty official to us!

Gwen and Gavin went to Lake Arrowhead earlier this month with their sons Kingston and Zuma, and in between time at the resort's spa and the pumpkin patch, it sounds like the family had a blast. Wonder what the family will be for Halloween?

On Tuesday Paris Hilton cruised around Los Angeles in her red Ferrari and the blonde heiress looked sizzling in a camouflage top. That's hot!

Paris is currently promoting her new single "Good Time," and during a recent chat with USA Today she weighed in on Miley Cyrus, whom she dressed up as on Halloween. "I think she's an artist and she's having fun, she's performing. She's looked really cute," Paris said of Miley's controversial MTV VMAs performance. Flattery will get you everywhere!

As far as Miley's performance and subsequent music videos sending the wrong message to young girls, P said, "No, I don't believe that. I think they know it's an artist performing. It's not real life. It's like a fantasy world. I don't think someone watches and says I need to do this or that ... I'm into girl power. I'm a huge fan of Britney, Katy (Perry). They are very inspirational. I love that there are so many women really singing fun songs."

Loves it!

Chris Brown has checked into rehab just one day after being released from jail on misdemeanor assault charges.

Brown's rep said in a statement:

"Chris Brown has elected to enter a rehab facility. His goal is to gain focus and insight into his past and recent behavior, enabling him to continue the pursuit of his life and his career from a healthier vantage point."

The R&B star and his bodyguard Christopher Hollosy were released without bail from a Washington, D.C. jail on Monday after their a felony assault charges were reduced to misdemeanors. The duo were arrested early Sunday morning after getting into an altercation with a man at the W Hotel who suffered a broken nose.

Brown and his bodyguard were charged with simple assault; Brown spent 36 hours in a Washington jail and was ordered to report to his California probation officer within 48 hours. The troubled singer is due in a Los Angeles court on November 20 for a probation status hearing.

So that's how the petite beauty keeps her fit form! We hate to see you go, Eva, but we love to watch you leave!

Eva Longoria got her workout going on Tuesday afternoon and damn is she looking' good! The 38-year-old star keeps her tight bod in tip top shape by getting in some cardio. Outfitted in black leggings, a black tank and gray sports bra, the former Desperate Housewives star was on the run from calories earlier today. We have to wonder if she is working on her physique for former flame Eduardo Cruz, who she is rumored to be back together with!

On Saturday, the couple, who broke up more than a year ago, were spotted in a passionate embrace during a romantic lunch at Serafina in New York City.

While it may look like the twosome are rekindling their romance once again, we have to wonder what's going on. On Thursday, X17online photographers caught Penelope's 28-year-old brother out to lunch both Olivier Martinez and a mystery woman. Eduardo and the brunette beauty even left the trendy LA eatery the Little Door together.

Hmmm?!

On Monday Salma Hayek shot scenes for How To Make Love Like An Englishman in Los Angeles, and the sexy star was joined by hubby Francois-Henri Pinault. Maybe he saw those pics of her boobs on display the other day and decided to stop by and supervise? Whatever the reason may be, we have to wonder if the spouses both planned on wearing matchy matchy navy blue outfits...

The movie is about a Cambridge University professor (played by Pierce Brosnan) who falls for Salma's character after knocking up her stepsister (played by Jessica Alba). We got photos of Jessica rocking a massive fake baby bump on set yesterday as well ... can't wait to see the first trailer for this flick!

Brr! It's cold out there! Hilary Duff and her adorable son Luca bundled up for an overcast morning in Los Angeles. The Cinderella Story enjoyed a low-key jaunt to the dog park with her tow-headed son and pups on Monday. Luca is such a little cutie we just want to put him in our pocket!

Despite a lack of makeup, the 25-year-old's skin looks flawless while carrying her 19-month-old. We have to say -- the natural look really works for her!

The singer/actress/mom kept things casual in gray sweats, a white shirt, brown Uggs and a fur-collared, olive green jacket. Little Luca wore yellow pants, brown sneakers and a furry blue hoodie.

These two are the picture of adorable! Mike Comrie is clearly a lucky man!
