The 50-year-old Beverly Hills, 90210 actress -- who is currently battling Stage IV terminal cancer -- was all smiles despite gearing up to testify under oath.

Taking to her social media, Shannen looked ready for anything that comes her way while snapping a smiling selfie with her dog, Bowie.

The star appeared strong and healthy while behind the driver's wheel and revealing she was escaping on an all-girls trip before heading to the courtroom.

Sitting in her car, Shannen turned the camera on herself and smiled while her German Shephard looked on.

Wearing an oversized sweatshirt, she rocked a black hat reading, "be here now," and a pair of aviator sunglasses.

Sporting a fresh face without makeup, Shannen captioned the cute selfie, "Road trip time with @missbowiedoherty Favorite thing about this photo is how Bowie is looking at me with such curiosity about our adventure." She also used the hashtags, "#roadtrip" and "#girlsbestfriend."

Shannen hasn't been spotted by paparazzi in months. The notoriously private actress' last Instagram post was over three weeks ago.
