The former TAKE THAT star, 30, fell for the sexy 21-year-old after meeting her in Los Angeles two weeks ago (FEB04).
Williams has been bombarding The Time Machine actress with text messages and sending her bouquets of flowers, in the hope she will dump American rocker BRIAN 'BRASCO' CASEY, of vocal band Jagged Edge.
A source close to the pair says, "Sam and Robbie just clicked as soon as they met. They got on like a house on fire.
"They swapped numbers and Robbie has been texting her ever since. He keeps asking her out but she had politely said no.
"She's happy with her American boyfriend Brian. But Samantha's very flattered. Robbie is one of the world's most eligible bachelors."23/02/2004 17:26
