My comparative paragraph

Britney Spears and Christina Aguilera are very different for some reasons. Britney is a mother of two children, while Christina doesn`t have anyone, she is still planing a family. If we talk about records, we have to notice that even though Britney has some good records such as circus, black out, and some others, Christina has fewer records than Britney. Another difference between them is that Britney has been in rehab because she is alcoholic, but Christina is healthier person, she never drinks and practices alot of sports. In my own opinion I think Christina is more talented than Britney, and she sings better.
