I like both, Jade being the only reason I like the Sugababes and I was majorly disappointed that her sold career was scrapped, but I really don't see anything wrong with what Rita said to be honest.
Jade doing Eurovision lead her to have a #35 solo single and joining a girlgroup that has bombed spectacularly since she joined. Not to mention leading her to appear on the most tackiest zeleb show ever. Her career has sadly done nothing but go down the can majorly since she entered the thing. Rita quitting has lead to three #1 singles and a #1 album. I'm not surprised she's seriously glad she quit.
There's no way Eurovision damaged Jade. We probably wouldn't even have known who she was but for the contest. It's a bit of an urban myth that Eurovision ends careers either.....last year's winner Loreen went to No.1 all around Europe (and #2 in the UK) and several other songs became chart hits.
