Ashton Kutcher and Demi Moore took a stroll in New York City yesterday afternoon.

Cameron Diaz hung out in the Manhattan streets as well.

Celebrity guests including Nelly, Jermaine Dupri, Janet Jackson, Usher, Ryan Cameron, and Monica attended the grand opening of Studio 72 in Atlanta yesterday evening.

Jermaine Dupri and Janet Jackson also attended. They have been together foreva! I don’t see why they don’t get hitched already!

Members of “The Hills” cast enjoyed cocktais on the beach in Malibu the other day.

Lauren Conrad, Brody Jenner, and Audrina Patridge were all seen, but where was Spencer and Heidi??

Angelina Jolie returned to NYC from her tour of duty in Iraq yesterday and took her three children, Maddox, Zahara and Shiloh to the Central Park petting zoo.

Looks like Mad gave up his rocker attitude for a more studious look!

Look at those chubby cheeks!  Adorable!

Justin Timberlake has been hanging in Chicago with a mystery woman.

Timberlake and a brunet went shopping in Chicago’s Gold Coast yesterday afternoon. They shopped at AG, Urban Outfitters and American Apparel.

Timberlake told people at AG he was in town to film “Oprah” on Thursday. Him and the friend seemed close. “They were talking about their families,” an eyewitness said.

No word on who the brunet is or where Jessica Biel was!

Nicole Richie and Joel Madden spent today in Central Park together in New York City.

Awww so cute! The couple are reportedly looking to buy an apartment in Manhattan.

Richie and Madden also shopped for baby clothes! Her next stop should be Victoria’s Secret. She should buy a bra since she has boobs now!

It’s nice to see Richie with some meat on her bones. She looks like a happy and healthy pregnant woman!

Lindsay Lohan is reportedly causing major trouble in rehab.

She apparently failed a mandatory drug test at her rehab center at the Utah’s Cirque Lodge, which means someone must be slipping her drugs in rehab. (It’s sad. That girl has few friends. Everyone in her life enables her and uses her!)

Read the full story here here.

In other Lohan-rehab news, she also reportedly got busted having sex with another patient in one of the facility’s bathrooms!

What a hot mess!

Here’s the other story.

I wouldn’t put this past her. I have friends who have hooked up with Lohan and this story is in line with her track record.

The crew of “The Dark Knight” blew up the Brach building the other day for a scene. This week is the last week for the filming of “Batman” in Chicago.

Jet-setting, UN Goodwill Ambassador, Angelina Jolie is in Iraq right now and will be visiting US troops. Jolie was in Syria on Monday and will be returning to its capital, Damascus, later tonight.

Go Jolie! We’re big supporters of our troops too! (Too bad not too many other celebrities have the balls or the dignity to go to Iraq to support those who are fighting for our freedom.)

Jolie is scheduled to reunite with Brad and her kids later this week. Speaking of, it seems they both have been traveling solo more often and spending more individual time with their children.

Yeah! Yeah! Yeah…yeah! So our friend’s mother got her nails done at the Orland Park Mario Tricoci recently. During her manicure, a blinged out brother sat down at the station next to her for a MANicure as well.

The Blingy Brother struck up a conversation with mom and asked her if she knew who he was.

When she said “no” he started busting out tunes.

After about four songs the mom still did not know who the hell was sitting next to her, but everyone else in the salon appeared to know and they were in hysterics.

Then the man began singing “I Believe I Can Fly”. Finally a song mommy dearest knew!

Turned out the super star at the salon was our friend R. Kelly. He’s known for his impromptu performances in random public places! LOL!
