This is shocking!

Selena Gomez is known for her squeaky clean image, but apparently the "Come & Get It" star did a secret stint in rehab last month, Radar reports.

The former Wizards of Waverly Place star checked-in to The Meadows facility in Arizona on Jan. 5, and although her rep confirmed the stay, they insist it wasn't for substance abuse.

The 21-year-old was reportedly "exhausted" and "broken hearted" following her split from Justin Bieber, but according to sources, she was also secretly dabbling with marijuana and prescription drugs, including Xanax and Ambien.

"Her friends and family became increasingly worried that there might be a serious problem with Selena. Particularly, her parents. The partying was, at times, wild. They wanted to help her - and they very much encouraged her to go to rehab. Others very close to her also urged her to seek professional help," one insider revealed.

The Biebs was apparently the bad influence, too!

"Selena came to understand just what a bad influence Justin had been on her life. Their relationship left her broken-hearted. I don't know whether Justin pushed her to drug use, but amongst their close knit group of friends, smoking was common place," another source added.

Now it makes sense why she announced back in December that she was canceling her upcoming Australian tour!

"My fans are so important to me and I would never want to disappoint them. But it has become clear to me and those close to me that after many years of putting my work first, I need to spend some time on myself in order to be the best person I can be," she said in a statement.

What is with young Hollywood these days?!

Sounds like a perfect way to spend a Tuesday afternoon after a weekend of work!

Yesterday Paris Hilton and boyfriend River Viiperi went shopping at Barneys New York in Beverly Hills, and the duo smiled and waved to fans and photographers before hopping in P's red Ferrari.

After that the heiress headed to Haus Of Milani on Melrose more a little bit more shopping. In case you're wondering why the name sounds familiar, it's because this is the same designer who made Paris' white hot Grammys dress. "Love all the new pieces that came in," P tweeted. "So many beautiful looks to choose from. #Lovesit."

Paris made an appearance at the Leather and Laces Superbowl Party at The Liberty Theater in Times Square on Friday, and over the weekend she DJed at The Pool After Dark at Harrah's Resort in Atlantic City. P then spent a day in New York before jetting back to Los Angeles ... knowing her, she'll be back on a plane before the week is over!

Just think, this coulda been Kim K!

On Tuesday afternoon Reggie Bush and fiancee/baby mama Lilit Avagyan went shopping for their nearly one-year-old daughter Briseis, and the parents looked casual and comfortable when X17 photographers snapped their photo.

Last year the NFL star revealed that he no longer keeps in touch with his famous ex. “We’ve been focused on the future,” Reggie told Life & Style. “I haven’t been worried about anything else or on anything in the past. Just the present and the future. I haven’t spoken to [the Kardashians]. I’ve just been focusing on my little girl and my family. That’s it really. I’ve been enjoying my life and this opportunity. All my focus has been on that.”

Sounds like he got the better end of the deal!

Justin Theroux, Joaquin Phoenix, Ethan Hawke and Bobby Cannavale were among the famous faces who stopped by Mimi O'Donnell's New York City home on Tuesday following the death of her longtime boyfriend, Philip Seymour Hoffman.

A funeral for late Oscar winner will be held in New York later in the month, and a rep for Hoffman added in a statement:

"In lieu of flowers the family requests donations be made in Phil's name to two charities that were very close to his heart: the DreamYard Project and the Christopher and Dana Reeve Foundation. The family wishes to thank everyone for their continued support and good wishes."

Hoffman's body was discovered in the bathroom of his West Village apartment on Sunday after an apparent heroin overdose. New York police have arrested four people suspected of having a connection to the drugs found in Hoffman's apartment, and according to the New York Post, Robert Vineberg, 57, and Thomas Kushman, 48, were arrested and charged with felony drug possession. Max Rosenblum and Juliana Luchkiw, both 22, also were arrested and charged with misdemeanor drug possession. The four were reportedly arrested in an apartment on Mott Street after police received a tip that the drugs found in Hoffman's apartment came from the Chinatown building.

Hoffman is survived by O'Donnell and the couple's three children, son Cooper and daughters Tallulah and Willa.

On Tuesday afternoon Kim and Khloe Kardashian lunched with their mom Kris Jenner at Fins in Westlake Village, and we're not sure if it was the best idea, but it seems like the ladies got on the family's trampoline after that!

It's hard to tell because Khloe is wearing the same outfit here that she wore the other day when her little sister Kylie had a minor accident on the trampoline, which is just further proof that their reality show is as scripted as House of Cards. Still, Khloe had a good sense of humor about it, as she posted a photo of herself and Kim and wrote, "Lady and the tramp..... You pick who's who." Ha!

P.S. Is it just us, or does it totally look like Kim's wearing her fav black workout spandex with gold heels here?



Love her darker 'do though!

Heidi Klum and her former bodyguard/boyfriend Martin Kirsten visited an attorney's office in Brentwood on Tuesday -- apparently to dissolve his employment contract after their breakup. Reports claim the two parted ways personally and professionally late last month ... so now begins the clean-up.

No doubt Kristen had an ironclad confidentiality agreement as part of his employment contract and when their professional relationship turned romantic, maybe the terms of that agreement changed slight. Now, as they've decided to part ways, it seems Heidi's bought in a lawyer to help make it a clean split. The two were very icy with each other this morning -- walking to their cars together, but not saying a word. And note Heidi's holding her big tote back in between her and Martin -- as a buffer. Neither said goodbye to each other when they parted ways and Heidi went home ... Martin Kristen went elsewhere. OVAH!

Last week People.com reported they had split after a year and a half of dating, adding that the breakup actually happened in early January.

"Martin was there for her during a challenging time in her life and it was something she will always be grateful for," a source told the magazine. "Life is about timing. He was incredibly supportive and they were there for each other, but they're moving on now. They still have a great friendship."

Selena Gomez grabbed lunch at Cici's in Studio City on Tuesday afternoon, and the 21-year-old starlet showed off her long legs in a pair of shorts and ankle booties. Hot! But seeing as it was in the low 60s today (not so hot), we have to wonder if the singer/actress was dressing like this to attract a little attention -- not from us, but from her on-again/off-again flame Justin Bieber! You know he's gonna see these pics, and aside from a certain pair of mustard-hued pants, Selena has been dressing to impress lately...

After all the legal troubles Justin has been through over the last few weeks (the D.U.I., having his home raided by cops and then getting charged with criminal assault), it seems as though Selena has been staying away from her ex-boyfriend, but we think it's only a matter of time before the two get back together.

Just one month ago the duo snuggled up in an Instagram selfie and Biebs captioned the pic, "Love the way you look at me," so maybe she can help set him straight and convince him to go to rehab and/or clean up his image? Or is he going to continue partying with trashtastic girls and getting in trouble all over the world?

What birthday present do you get for the popstar who has everything? A court date! A Miami-Dade County judge has set a trial date for Justin Bieber's three misdemeanors for March 3, just two days after the lil' bad boy's 20th birthday.

On January 23, the sizzurp-swigging miscreant was charged in Miami Beach for driving under the influence, resisting arrest and driving with an invalid license. Bieber admitted to police that he had been drinking, smoking pot and taking prescription medication. Police also believed that the "Beauty and the Beat" singer was involved in an illegal drag race between himself and R&B singer Khalil Amir Sharieff. Sharieff was also arrested on a DUI charge.

Initial trial dates are often delayed so it's possible that this trial will be moved. The Bieb's arraignment date was set for Feb. 14th, however since his lawyers have already filed a written plea of not guilty -- his case goes to trial immediately.
