LONDON: The 27-year-old actress was spotted partying with her younger brother Christian's friends in Mississippi last weekend, and was particularly taken with one 22-year-old stud. A source is quoted by FOX 411 blog as saying: "Kirsten met a cute, young, guy at a bar in Oxford, Mississippi, and they partied together and had a hot little hook-up. She invited him back to her hotel and even took him out for breakfast in the morning. She was having a good time, and she likes younger guys." Kristen - who received treatment for depression at Utah's Cirque Lodge rehab centre last year - was in Mississippi enjoying a relaxing summer vacation. Kristen has been spending lots of time with Christian recently - last week she threw him a party at Los Angeles nightspot Madame Royale. A source said: "She came alone without a date and Christian brought several of his buddies. Kirsten and Christian are very close, and they get along with each other's friends. Everyone was drinking vodka and partying at their table. Kirsten looked like she was having a great night, laughing and dancing with all the young dudes."
