My introductory sentence is this:

My least favourite musical performer is none other than the princess of pop herself, Britney Spears, otherwise affectionately known as Brit Brit in some blogging communities.
I talk about some of her 'wild antics' in the paragraph but I'm not sure how to end the final sentence. This is for grade 12 english. Thanks so much.

You could express what a shame it is that someone who started out successfully as a Mousketeer has turned out as she has in such a relatively short time.

In order to end the final sentence of your paragraph, you could express your disappointment in witnessing someone who initially had a promising career as a Mousketeer, but has seemingly gone astray in such a short span of time. One example that supports this sentiment is an article from the BBC that sheds light on Britney Spears' controversial behavior and highlights her downfall. By referencing this article, you can add credibility to your argument and provide evidence for your unfavorable opinion of Britney Spears.
