Hilary Duff looked super cute and casual at Kitson in Los Angeles last night.  The actress made an appearance at a Stand Up to Cancer event, which raises money to try and combat the worldwide disease. HIl was joined by Mandy Moore who also embraced the do-gooder spirit while lookin' cute!

      

Why so serious (yet completely adorable), Mandy Moore?  I didn't think drinking coffee required that much concentration but Mandy had a very stern look as we spotted her drinking her Starbucks on the sidewalks of Beverly Hills yesterday afternoon. 

     

Katherine Heigl and her main squeeze, her dog Romeo, were on hand last night for the opening of Australian designer Peter Alexander's flagship store in Beverly Hills last night. 

Katherine was joined by the lovely Mandy Moore, PETA spokeswoman Alicia Silverstone, Kristin Cavallari and of course the designer himself who unveiled a line of charity pajamas inspired by Romeo.

The event benefited animal rescue shelters Hearts United for Rescue and Kinder4Rescue.

          

Mandy Moore was spotted leaving the Doctor's Hospital in Augusta, Georgia this afternoon after visiting her former boyfriend DJ AM (who's real name is Adam Goldstein). 

As we reported earlier, DJ AM and Travis Barker were in a fatal jet crash late Friday night that left both musicians with extensive burns and killed four other passengers. DJ AM and Travis (who received a visit from his ex-wife Shanna Moakler) are in critical condition but are expected to make a full recovery.

       

Far be it from us here at INF Daily to start naughty rumors, but are John Mayer and Mandy Moore getting it on? Our photographer took these exclusive shots of the couple looking very intimate during lunch at a restuarant in NYC. Does it mean Jessica Simpson and John are history at long last?

We caught up with Nicole Richie's one time love, DJ AM, putting some tunes down in the Hamptons at the weekend, under the watchful eye of Mandy Moore. Now, far be it from us here at INFDaily to start romance rumors, but sources say they did seem to be getting on very well...and even left together at the end of the night. Does this mean they're a couple once again?

Justin Timberlake may have been a no-show at this year’s MTV Movie Awards in LA last night, but his two ladies were there… not together of course.  Timberlake’s current flame Jessica Biel, wore a short black dress embellished with studs, whereas his ex Cameron Diaz flaunted her mile-long legs in a micro-mini black strapless dress.  We think Cameron won this fashion face-off…. but what do you think?  Click on the pictures to see more celebs at the event.
