Mischa Barton donned a pink one-piece bathing suit as she and her boyfriend Sebastian Knapp enjoyed a day on the beach in Ibiza, Spain today (July 27, 2012).

The couple shared a kiss and then swimming in the water together.

Mischa seems to be a fan of pink. She wore a pink dress with stars on it just the other day. However, she did forget to wear her underwear.
