Gosh I feel old! A lot of us used to watch actress Mackenzie Rosman on the popular show 7th Heaven back in the 90’s, and she was a teeny little thing then. However, she’s not so teeny anymore…and now she’s showing off her bikini cakes for Maxim! 23-year-old Mackenzie recently posed for the issue, and she’s looking ah-maz-ing! Check her out in the gallery.
