says her biggest thrill in life is bottling her own spring water.
The 'On the Road' actress - who was once famed for her party girl lifestyle and went to rehab in 2008 - often goes on trips to various springs across Europe as she says it's fun to do something that doesn't involve alcohol or wild nights out.
She said: "I'm planning to drive through Switzerland and look for other springs; it's fun to do something other than drink a bottle of wine, to find things that adults can do that are fun. My dad is German, so he's all about bike rides and nature."
Kirsten loves taking road trips because she doesn't know where she's going to end up.
She said: "I've been on a road trip with my dad through Germany before, and one with my girlfriends across the US. I would do that again. It's fun to explore, and get lost and not know where you're going to stay."
However, the 28-year-old star is enjoying being settled at the moment and getting to spend time with her friends and family.
She added in an interview with WWD: "I was gone for so long working, I missed everybody, and so I've been living at my mom's house all fall."
