She's back! Sort of...

Leann Rimes entered treatment for emotional issues earlier this month, but the Grammy winning singer is not letting her recovery get in the way of her career! The country cutie is headed to the Midwest for a series of concerts, and she couldn't be happier about reuniting with her loyal fans.

"I'm on a plane headed to see all my fans in Wisconsin tonight. I can't wait to play, I'm so ready. I've got a zillion fashion mags, my journal, iPod, water and a butterfinger. I'm all set," she wrote in a blog post titled "Back At It."

Wait... this slender stunner eats candy? According to the 30-year-old, with age comes an increased love of sweets!

"Seems I've developed a sweet tooth after turning 30. If that's all that comes with 30, I think I'm settling in pretty well. So far, the new decade is treating me great! Hope you all have a fantastic weekend and I look forward to seeing all of my fans and friends over the next 3 days," she added.

Scheduled to perform in Iowa and Indiana this weekend, followed by concerts in Maine, Colorado, and California later this month, the blonde beauty seems happier and healthier than ever after coping with reported overwhelming anxiety and stress.

"I have the best fans ever! Thank you for all your prayers, patience and unwavering love xoxo," she tweeted.

We couldn't be happier for Mrs. Cibrian that she's sorted out her issues and is back to doing what she loves - putting on an amazing show!

Does she ever take a day off the gym?

Hilary Duff strolled through West Hollywood on her way to a workout yesterday, and the Lizzie Maguire star opted to wear a red leather jacket with her fitness gear. Considering temperatures are soaring in California, you would think the 24-year-old would ditch the winter wear!

When the blonde beauty isn't sweating off the pounds these days, apparently she's bonding with none other than Lindsay Lohan! The former frenemies have reportedly buried the hatchet, and are now texting nonstop! The redheaded rehabber allegedly thinks the Disney star is the kind of stable, responsible friend she needs in her life.

"[Lindsay] feels like Hilary could be a good influence - she has a healthy marriage, just had a baby and doesn't care about clubbing. Hilary has already put the word out to her husband, Mike, to think about potential setups for Lindsay," a source divulged.

Poor Mr. Comrie! Finding a suitor for Lilo doesn't sound like an easy task!

Can you believe she's 54-years-old?!

Sharon Stone went on a stroll through Beverly Hills yesterday, and the Basic Instinct star looks like she hasn't aged a day since becoming one of Hollywood's biggest sex symbols! We wonder what her secret is?

Normally we would assume it was botox or some other plastic surgery procedure, but her looks are so natural she must be one of the lucky ones that gets better with age!

The blonde beauty has been dating 27-year-old model Martin Mica for the past several months, and apparently the Total Recall actress makes young guys swoon!

"I really get pursued by men in their twenties, like, a lot. They probably know there's food in the fridge and that somebody's there to talk to them and ask them how their day was," she was once quoted as saying.

When you look this good we can see why!

Talk about a fashionable get together!

Kris Jenner, as well as daughters Kendall and Kyle, joined Kendra Wilkinson and Lucy Hale for Fashion's Night Out in LA.

After catching a show, looks like the sisters bonded with their cell phones. And we can't help but notice that Kris Jenner's nose looks a bit different. Hmmm...

Regardless, these ladies all look pretty fab!

Lily Rose Depp may be a young fashionista, but she skipped heading to a fancy department store ... instead opting for Goodwill.

The 12-year-old daughter of Johnny Depp and Vanessa Paradis, who was wearing a black bustier-type shirt and cropped jean shorts, seemed to be dressed a little mature for her young age. We think Lily's friend seems to be dressed more appropriately for a pre-teen.

Then again, when your dad is worth millions, the normal rules must not apply.

For someone whose job it is to critique designer's creations, we would expect more from her!

Heidi Klum attended a Fashion Night Out event in NYC last night, and the Project Runway host decided to wear a black and white pantsuit that resembled a race car driving outfit. Call the fashion police!

The German model might be too distracted by all the turmoil in her personal life to care about her style lately! Her scorned ex Seal ruffled feathers recently after accusing the blonde bombshell of cheating on him with her longtime bodyguard Martin Kristen, which she denied.

Not only that, but reports are claiming that the "Kiss From a Rose" singer is demanding more money in the divorce settlement and joint custody of the couple's four children.

Hopefully Heidi has some money left over to hire a stylist after all is said and done!

We love that Mariah Carey is back to her sexy songstress shape, but what we're not lovin' is this overly snug black dress with ruffled bottom. Yikes!

Someone call the fashion police STAT!

Not exactly something we'd say seemed comfortable to travel in, but Mimi felt like rockin' this black number and black heels to catch a flight from New York to LA.

Good thing the American Idol judge's outfit is for the airport runway ... and not the fashion runway. And how hilarious refreshing is it to see Nick Cannon's wifey cruising through security just like the rest of us.
