2010 was a year full of wonderful beginnings for some, humiliating endings for others and all around drama! Here are the top 10 most memorable moments that happened in the entertainment world this year. Ready, set, lets go!!!

10. Katy Perry

Ms. Perry has had quite a year. The only negative was her infamous "Sesame Street" video, which was pulled before it aired on the children's show. The reason: Her outfit showed too much cleavage. Aside from this little mishap, Perry had a stellar year. She wed comedian Russell Brand in a lavish wedding in India; her album "Teenage Dream" was nominated for a best-album Grammy, and she rocked the stage at the "VH1 Divas Salute the Troops" concert. Perry was all over the place in 2010, and whether the publicity was good or bad, she made her presence known.

9. "Spider-Man on Broadway"

It's the most expensive Broadway production in history ($65 million), yet it has had the most mishaps. "Spider-Man on Broadway" kept pushing back its opening date because of accidental falls by stunt devils and actors during previews. All that money for a production that has become the most dangerous show on Broadway.

8. Lindsay Lohan

Oh, Lindsay, where shall we begin? Lohan was in the headlines just about every other day for violating her probation, going to court and then heading to the Betty Ford Center. Just when we thought our LI girl was getting better, there were reports that she sneaked out of the center to get alcohol and allegedly attacked one of the staffers at Betty Ford. Let's hope the new year means sobriety for Lindsay.

7. Lady Gaga

Fashion icon, activist and scandalous: This year, she was all three. From her meat dress at the VMAs, to her leading "Don't ask, don't tell" rallies, to her much-talked-about racy video with Beyoncé, "Telephone," Lady Gaga made sure her presence was felt in 2010. Oh, yeah, and her album "Fame Monster" was nominated for Grammy album of the year. What a way to end an unforgettable year.

6. "Glee"

Our favorite musical teens had a great year and constantly made headlines. Cast members faced drama with the backlash over their provocative GQ cover, and there were rumors that the beloved crew would be "graduating" and replaced with a new cast. On the bright side, they lead the Golden Globes with five nominations, and they had just about every celebrity in the world on their show this year.

5. "Lost" and "24"

Sadly, we said farewell to both shows. "24" had a great run, beginning in 2001, and its end in May still left fans wanting more. "Lost" fans mourned as the show concluded with everyone dying, but all good things must come to an end.

4. "American Idol"

Simon Cowell, the loudmouth who often sent "Idol" hopefuls home in tears, made his exit from "American Idol" this year to be the executive producer and judge on another show, "Ex Factor." His sarcasm and wit will be missed. Jennifer Lopez and Steven Tyler joined "Idol" as the new judges, leaving your favorite dawg Randy Jackson as the only original judge.

3. Mel Gibson

Gibson's vile rants toward his now ex-girlfriend Oksana Grigorieva were heard all over the world. Mel has made degrading comments about other people and groups, but these were among his worst.

2. Sandra Bullock

Everyone's heart went out to Sandra Bullock this year. She reached the pinnacle of any actor's career by winning an Academy Award for best actress for her role in "The Blind Side." She gave a heartfelt speech in which she thanked her husband, Jesse James, for being such a great supporter, but it soon came out that he had been cheating on her. Then she announced that, newly single, she was going ahead with her adoption of a baby. Talk about a year full of highs and lows.

1. Conan O'Brien

Our No. 1 spot goes to funny man Conan O'Brien. He was knocked off NBC to make room for Jay Leno, but he signed with TBS to host a new show, "Conan." The buzz was huge, and to many he didn't disappoint and is still the king of late-night TV.
