Mischa Barton rocks a black blazer and a pair of skinny jeans as she holds onto a black valise and a tea from Starbucks in Los Angeles

She first gained attention as one of the creepy ghosts in 1999’s eerie masterpiece The Sixth Sense.

And Mischa Barton was seen looking a lot more grown up in Los Angeles, California on Tuesday, when she was spotted stepping out to buy some flowers at the market before making a stop to get an afternoon caffeine fix on her way home.

The O.C. star, 34, wore a sensible black blazer over a white t-shirt with red writing.

She paired this with formfitting skinny jeans. 

Barton sported white footwear, and clutched a black leather valise with gold buckles.

She had on a light blue face mask, and wore a single gold pendant around her neck.

Mischa also accessorized with gold earrings.

The actress let her blonde hair hang long and loose, and parted it in the middle.

Barton was last seen late last week with her boyfriend Gian Marco Flamini.

The Hill: New Beginnings starlet was first linked to Gian Marco earlier this year, and the two have been nearly inseparable ever since.

On the acting front, Barton has a somewhat bizarre-sounding new film in the works. 

The film is called DragonMan: The Adventures of Luke Starr, in which Mischa will portray Crystall Starr.

The movie, currently in pre-production, is based on the DragonMan book series by Ted Lazaris.
