Throughout the years, celebrities have shown changes in their lives - looks, outfits, favorites and people they work with.

Have you ever watched a celebrity and become a fan remembering how he first started in Hollywood? If yes, you would know how he first looked a few years back when he was just starting.

Britney Spears started as a teenager. Her first single, "Hit Me Baby (One More Time)," was a hit that brought her to fame and for many years people have been trying to see her perform whenever she is around.

Carmen Electra was one of the well known originals of "Pussycat Dolls," where she gained fame after joining the burlesque group. Christina Aguilera started singing at the time of Spears's popularity. The two were known as rivals in the music industry.

Some stars on the list seemed to have gone to age. Celebrities like Jennifer Anniston became noticeable in the popular sitcom, "Friends." She is now doing well in movies and currently engaged to Justin Theroux.

Tom Cruise is one of the very few stars that look exactly like he was when he started, still handsome and looking good as ever. What can you say about these celebrities? Do they look better then or now?

Check out the list of celebrities that have been in Hollywood for years and have changed quite a bit in their looks, but some look better now.
