Mischa Barton & Cisco Adler Engaged

Mischa Barton (star of the OC) announced her engagment to 26 year old Cisco Adler... the ex-fiance of Kimberly Stewart... the daughter of Rod Stewart. If you remember, Kimberly Stewart made news last week announcing her enagment to 18 year old (she's 26) Talan Torriero (of MTV's Laguna Beach ) after just weeks of dating. They promptly broke of the wedding and the relationship.

"Mischa Barton, 19, has apparently accepted the marriage proposal of 26-year-old Cisco Adler - Kimberly Stewart’s ex-fiancé after he got down on one knee in Hawaii. For those of you that don’t know who Cisco Adler is - he is a singer with Whitestarr and was formerly engaged to rocker Rod Stewart’s daughter."
