Jennifer Garner made a rare appearance in her bikini yesterday while on the beach in Hawaii with Violet! The hot mother of two first strolled along the sand in her red cover-up, then stripped down to reveal her mismatched two-piece. Violet and Jennifer are in the midst of a fun family vacation, and they explored the surf over the weekend alongside bearded Ben Affleck and little Seraphina. The Garner-Afflecks just wrapped up another year of adorable moments, and it looks like 2011 is off to a similar start. Their getaway wasn't just to ring in the New Year, however, as Seraphina's second birthday is coming up on Thursday.
