Rachel Bilson is convinced that she is "losing her mind."

The 30-year-old actress often loses track of her personal items.

Rachel is astonished by her lack of awareness at times.

"I think I'm losing my mind," Rachel told People magazine. "I sat in my car for ten minutes the other day thinking my windows were broken, but the car was off. I literally forget everything I do. I can't find anything. I don't ever know where I put my keys."

When she is not looking for misplaced items, Rachel is exercising. Although she is a bit awkward on the court, tennis is fast becoming one of her favorite pastimes.

"I'm learning tennis, but I'm only comfortable with my forehand, and therefore I run to the opposite side of the court just so I can use it," Rachel explained. "I'm not very good."

Rachel loves sporting, but the actress is not interested in pursuing any tattooing with her free time in the future.

"I don't have any [tattoos]," she shared. "I used to have a belly-button ring and eight ear piercings. I got the belly-button ring when I was really young, and the hole hasn't closed up. Yeah, I think I'm done."
