Pop diva Taylor Swift took home an armful of trophies at the Billboard Music Awards on Sunday. Swift, 23, in a figure-hugging blue Zuhair Murad mini-dress, collected eight awards including top artist, top female artist and top Billboard 200 album for her latest release \"Red,\" which has sold more than 5.4 million copies worldwide. \"You are the longest and best relationship I ever had,\" Swift told her fans, turning her tabloid reputation as a serial dater to her advantage, AFP reported.
