Gisele Bundchen knows how to heat things up!

Over the weekend the Brazilian supermodel posted the above throwback pic of her and husband Tom Brady engaged in a very passionate kiss, and she wrote, "Happy birthday my love! Missing you so much... Te amo!!! Feliz aniversario meu amor! Estou com muita saudade... Te amo!!!"

Tom might not understand the entire written message, but we're guessing he totally gets the picture. Love this hot couple!
