Jennifer Aniston covers Marie Claire July 2011 wearing nothing but an Ann Demeulemeester jacket and Gucci briefs. The 42-year-old actress and her 'Horrible Bosses' co-stars, Charlie Day, Jason Bateman and Jason Sudeikis, are featured inside the magazine where they talk about their life at work before being famous, underemployment, and their first jobs and how they spent their first big paycheck.

Jennifer Aniston is the new cover girl of Marie Claire July 2011. Still, the 42-year-old actress didn't make the shoots alone, but along her 'Horrible Bosses' co-stars, Charlie Day, Jason Bateman and Jason Sudeikis. Inside the magazine, Jennifer talks about her first job and how she spent her first big paycheck, about having horrible bosses and what she would do if she wasn't an actress.

"Maybe an interior designer. I love seeing a house and thinking about how it should be redone or restored. I spent a lot of time doing my current house, and it’s beautiful… It’s like a beautiful work of art, and I’m very proud of it. But I recently realized that I'm into cozier spaces. My house is too big. I love to entertain there, but most of the time the house is empty. I just live in one room, and I don't need all of the space. Now I get to do the fun part again and look for a new one," Jennifer told 'Marie Claire'.

Speaking about her first job, Aniston recalls she appeared on her father's soap opera, "as an extra on my dad's [actor John Aniston] soap opera, 'Search for Tomorrow'. When I was 12, I asked him if I could get a part on his show. I wore a yellow skating outfit, and I was kinda large. It's hard to look good in yellow, and I certainly did not. I remember I got a check for about $100, and I was blown away. Later, I waited a lot of tables, and I wasn't very good at that. I dropped more than one Alpine burger in customers' laps, and you just do not want all of that Swiss cheese and mushrooms in your pants. I wasn't a good waitress, but I was told that I was very nice and charming, so people liked me anyway," she says.

The lovely actress also remembers on what she spent her first paycheck. "I spent my first paycheck on a vintage Mercedes. I was struggling a little in New York, working as a waitress at Jackson Hole but not really getting any consistent acting work. Then I moved out here to Los Angeles, and I started getting pilots and working pretty regularly. I still didn’t make any decent money until I got on Friends. Practically every day for about a year, I'd drive by this beautiful car that was parked on Melrose near Fred Segal with a "for sale" sign in it. It was a beautiful little vintage Mercedes 280SL. I had it fixed up, but it never worked. It was a lemon. Now I know why it was on the street for so long! I may have driven it three times, but I held on to it forever. It really represented something to me."

Jennifer admits she never had a horrible boss, but confesses that it was extremely funny playing one in her latest movie, 'Horrible Bosses'. "I had a fantastic time playing one. Honestly, the character is so absurd. I'd never done anything like this part. It was degrading and uncomfortable for Charlie, and it was really fun for me," Jennifer says.

Jennifer is currently working on a short film about the impact of breast cancer. "Right now, I'm directing a short film with Patricia Clarkson and Tony Shalhoub for Lifetime's Project Five, an anthology of short films about breast cancer. I'm trying to be a good boss – to have a good temper, know what I'm doing, have everything in order. I think it's just about creating a positive environment. If you're going to kill'em, you gotta kill'em with kindness," she told the magazine.
