Jessica Alba was spotted leaving Katsuya in Brentwood last night, and earlier in the evening she attended an event for her latest business venture, The Honest Company. Jess tweeted this shot and wrote, "This is how cool I am @KellySawyer called me out 4 still wearing my name tag at dinner -in a restaurant." Ha!

Ashley Tisdale ditched her rockstar beau Martin Johnson for the day, and instead, spent the afternoon with her girlfriend.

Tisdale rocked a flowy white top and skirt ... mixing it with a floppy hat and scuffy black boots. Not sure about those boot buckles, Ash!

The former High School Musical hottie has just landed a role in a new CBS comedy pilot which will focus on "creative young people that are trying to achieve their dreams during these tough financial times."

We're lovin' that the Tis is showing a lot of leg. You go, girl!

Steven Tyler is saying aloooooooooooha to a lavish new Hawaiian hidaway!

The American Idol judge purchased this 3,000 square-foot estate in the Kihei area for $4.8 million.

Tyler's home boasts two bedrooms, 3 bathrooms, exquisite kitchen, open air sleeping porches, flagstone floors and breathtaking ocean views.

The oceanfront property was originally listed for $6.5 million. See more of the impressive pad in the gallery below.

Jennifer Lopez covers V Magazine's Sports Issue, and the 42-year-old actress strikes a series of sexy poses in boxing gloves ... and not much else!

The actress/singer also chats with the mag about her ex-husband Marc Anthony, and she seems to be handling their split quite well. “I mean, we’re parents and friends first," she says. "That will be the thread that ties us together. I don’t know if people expect it to be negative just because the relationship didn’t work out.” Of course, having a hot new romance with Casper Smart probably helps too!

J. Lo talks about making mistakes, telling the mag, “You’re not going to hit the target or the bull’s-eye every time. That’s part of it. At the end of the day, I made those choices. I’ve been in the business now, I don’t want to say how many years. You have amazing moments of recognition and success. But at this point in my life, I try to take it all with a grain of salt.”

So what about the significance of this photo shoot? J. Lo learned how to box for Money Train, and she studied krav maga for Enough, so this isn't all acting! “I know how to fight!” she declares proudly. "I can take a lot of punches and still keep going. I’ve been trained like a boxer to go 15 rounds." Looks like she's still Jenny from the block!

Justin Theroux enjoyed an afternoon at The Chateau Marmont with two ladies ... none of which were Jennifer Aniston. Must of been an important business meeting!

The Wanderlust star, decked in all-black leather, has been working hard to promote his latest flick ... but all of his promotional airtime didn't help the movie's debut weekend. The movie flopped at the box office with $6.6 million opening weekend.

The silver lining is that Theroux met his sexy ladylove on the set. Sounds worth it to us!

Nicole Richie looks oh-so-glamorous in the latest issue of Ocean Drive, but the former party girl wasn't always so chic. But the mama of two has no regrets for getting crazy during her Simple Life days with Paris Hilton.

The 30-year-old fashionista tells the mag:

"I have very fond memories of that time! You have to remember that I was 20 years old. I don’t know anybody who can look back at who they were at 20 and say, ‘I’m the exact same person."

Richie, who was arrested for DUI in 2003 and 2006, spend time in rehab to battle her addictions. What a difference ten years makes!

Before heading to the Vanity Fair Oscar party on Sunday night, Miley Cyrus took a few minutes to tweet at a handful of users who have been sending her nasty messages and death threats!

Miley tweeted at @TheCyrusSlut (responding to a message which has since been deleted), "I'm surrounded by love I'm sorry 4 whatever happened 2 make u so bitter."

The former Hannah Montana starlet wrote to a different follower, ''I won't tolerate someone telling me 2 die," adding, "I think Twitter needs to take some responsibility and make it a safe environment." Aww Miley! We love you, so don't get too frazzled about it!

But should Twitter make more of an effort to block hateful tweets like this?
