Bristol Palin says that Levi Johnston proposed to her by putting rose petals in the shape of a heart on her bed. After she saw it, he got down on one knee to ask her the big question, Palin explains in a video for Us Weekly as Johnston’s face reddens. The couple, who announced their wedding plans on the cover of the magazine, said the news was a surprise to Sarah Palin, the mom of the bride-to-be. Palin has been critical of Johnston’s antics, including his Playgirl spread. The younger Palin says, “It just feels right to be a family.” Johnston adds, "I've missed out on a lot of his life, and I can't get that back… Seeing him walk or crawl for the first time, or his first word ... I missed all that. More importantly, I am here now, and I am going to make it right."
