Mary-Kate Olsen has impressed bosses on the set of her latest TV show. The actress - who shot to fame alongside twin sister Ashley at the age of nine months when they played the role of Michelle Tanner in the sitcom 'Full House' - makes a one-off appearance in comedy 'Samantha Who', playing a self-destructive bad girl.

However, she was nothing like her alter-ego when she turned up on set. The show's executive producer Don Todd said: "She showed up alone, ready to work, is great on set and is serious about the job. This is a girl who's been in front of the camera almost literally her entire life. She's smart, and she knows what she's doing."

Actress Mary-Kate Olsen appears on the cover of the July issue of Elle magazine, and inside she talks about Heath Ledger and the paparazzi.

It has been five months since Ledger died, and Olsen still refuses to talk about the fact that she was the first person called when he was found dead in his apartment. "I'm not going to comment on that," she told Elle. "I won't give you a word about that in the nicest way possible. Let's move on."

Kirsten Dunst has reportedly been released from rehab at Cirque Lodge in Utah and has been spotted in New York City.

In Touch reported earlier this week that Dunst had been calling friends to apologize for her behavior while she was drinking. The report also claimed that she called Tobey McGuire, ex-boyfriend and co-star in the "Spiderman" movies.

Ashley Olsen has blasted the paparazzi - labeling them "weird and scary."

Ashley, whose twin sister is Mary-Kate Olsen, has been famous since she was six-years-old but admits she still finds it difficult to deal with photographers following her.
