Kat Graham sported a cute colorblock bikini while strolling near the beach in Santa Monica, CA, on Monday. The Vampire Diaries star was joined by her fiancé, actor Cottrell Guidry, and her cute pooch, Izzy, to enjoy the warm LA weather — you've got to love hitting the beach in October! The couple held hands and kissed while walking down the street before showing off their beach bodies on the sand. Kat has been keeping busy lately and balancing work, play, and wedding planning. The fifth season of her hit CW show premiered earlier this month, and she was also on hand to speak on stage at September's iHeartRadio Music Festival. While Kat and Cottrell got engaged in October 2012, she bride-to-be said in a recent interview that the two are "already are kind of married," adding, "I'm just planning a party."
