Kate Hudson may have just split from fiance Matt Bellamy, but she certainly doesn't have the breakup blues!

On Tuesday night the 35-year-old actress visited with BFF Sara Foster, and we also spotted Nicole Richie arriving at Foster's Los Angeles home. Girls' night in!

Even minus the makeup, Kate was totally glowing -- might this have something to do with the fact that she has been hot and heavy with Dancing With The Stars pro Derek Hough since splitting from her baby daddy?

Kate and Derek were spotted making out at The Nice Guy in Hollywood last Friday, and on Monday her rep confirmed what X17 first reported -- that Kate and Matt had parted ways. But given the Almost Famous starlet's track record with men, will this rebound romance with Derek last?
