Sienna and Orlando Bloom

By THOMAS WHITAKER Showbiz Reporter SEXY Sienna Miller gives cheating fiance Jude Law a taste of his own medicine — by snogging Orlando Bloom. Blonde Sienna, 23, cuddled Lord of the Rings star Orlando, 28, and gazed into his eyes during a heart-to-heart. The couple — who had a fling four years ago — oozed sexual chemistry at a polo tournament in Windsor, Berks. An onlooker said: “They spent ages cuddling, kissing and gazing at each other. There was real chemistry.” The couple met up again later and sat with their legs entwined around each other. Sienna was devastated after Jude cheated on her with nanny Daisy Wright, 26. She said: “I’ve had a pretty dreadful week, but I’m bearing up.” Jude, 32, has moved into a hotel near their £2million home and still reckons he will wed Sienna. His spokesman insisted: “They’re still engaged.” Credit: www.thesun.co.uk
