Kate Bosworth stepped out solo for an outing in LA yesterday. She was without her usual companion, fiancé Michael Polish, with whom she shared a romantic moment earlier this week. On Wednesday, Michael tweeted a quote to his future bride that read, "It was the kind of kiss that made me know that I was never so happy in my whole life." Apparently, the feelings were mutual, as Kate retweeted the passage to her own followers as well. This is not the first time the couple have revealed their love via social media. Last month, Kate posted a picture of her ring shortly after leaking the news of her engagement in the August issue of Vogue.
