Paris Hilton is in Vancouver filming a guest-star appearance on TV series Supernatural.

The actress was swarmed by fans when she arrived at Vancouver Airport on Monday, decked out in all black, wearing dark sunglasses and a black cap. After arriving in the city and signing autographs for fans, she hit downtown Vancouver for a spot of shopping.

"Just got back from walking around downtown Vancouver. Went to HMV and bought LMFAO's new album. So sick! Loves it! I'm in Vancouver B*tch ;)," she tweeted to fans.

The blonde heiress spent the day Tuesday filming.

"Still on set shooting, the scenes are going great! A lot of stunts and fighting scenes! :)," she tweeted to fans Tuesday afternoon.

And earlier in the day: "On set shooting, everyone is so nice. Having so much fun! I Love playing this character, so fun! Loves it! :)"

The socialite is playing a demonic creature on the show, which is set to air in November.

Here are a few of Paris's twitter feeds:
