Never thought about Britney Spears... Jessica Alba on the other hand, absolutely. Wouldn't even need to go back in time. She's just one fine and sexy lady.
When I travel in time, I am going to buy stock in IBM, Coke, Pepsi, McDonalds, Warren buffets company Berkshire Something, Tesla, Microsoft, Apple, and of course banks.... Put 10,000 into a Templeton mutual fund....
