After months of primping, preening and attempting to deal with uproarover thelack of diversityamong Oscar nominees again awards season is officially over in Hollywood.

The world cannowrest easy knowing thatLeo finallyhas hisAcademy Award, and also that he holds no grudges against Rose for letting him sink into the sea (even though they both couldhave fit on her raft.)

ActorsLeonardo DiCaprio and Kate Winsletdelighted Titanic fansby posingtogether on the red carpet ahead of thisyear's Oscars ceremony, sparking a #TitanicReunion hashtag despite the fact that they weren't actually reuniting.

Many on Twitter encouraged the longtime friends to "never let go" as they shared pictures of their characters, Jack and Rose,from James Cameron's1997film.

What really choked viewersup, however, was the shot of Winslet's joyful reactionwhenDiCaprio won his first-ever Oscar for best actor in The Revenant.

Here are four more of the most buzzed-about andmemorablemoments from 2016Academy Awards ceremony:

Chris Rock's fiercemonologue

Second-time Oscars host Chris Rock pulled no punches in his opening monologue,choosing to address the #OscarsSoWhite controversy head on with his first line and almost every line after that.

"Man, I counted at least 15 black people on that montage," he started."I'm here at the Academy Awards, otherwise known as the White People's Choice Awards.You realize, if they nominated hosts, I wouldn't even get this job."

Serious as the subtext might have been, Rock brought plenty oflevity and laughter to the room through his signature sense of humour.

"Jadaboycotting the Oscars is like me boycotting Rihanna's panties. I wasn't invited," said the 51-year-old comedian, referring to actressJada Pinkett Smith. "But I understand, I'm not hating. I understand you mad. Jada's mad her man Will was not nominated for Concussion...it's not fair that Will was this good and didn't get nominated.Yeah, you're right. It's also not fair that Will was paid $20 million for Wild Wild West.OK?"

The speech was a hit among audience members, both at home and in theDolby Theatre in Los Angeles on Sunday night.

Jacob Tremblay geekingout over Star Wars droids

This year's Oscars broadcast taught us that even the most charming and composed childrencan be tempted to jump out of their seats when robots enter the room.

Nine-year-old Canadian actor Jacob Tremblay, who starred in best picture-nominated Room, was adorably stoked whenBB-8,R2-D2, andC-3POfrom Star Warsrolled on stage as part of a tribute tolegendary composer John Williams.

The noted Star Wars fan was spotted craning his neck around taller audience membersto get a better look at the droids in action,coaxinga collective "awww" out of viewers at home.

The young actor also got some attention online ahead of Sunday's showfor posting a photo of his"hot"parents on Instagram. They don't seem to mind.

Stacey Dash's inadvertent self-burn

In what must be one of the most cringeworthymoments in recent Oscars history, 90's actress-turned-Fox News contributorStacey Dash made herself the butt of Rock's joke simply by showing up.

Dash, whojust last month said that Black History Month shouldn't exist and called the#OscarsSoWhite boycott "ludicrous,"has been criticized in recent years for her various comments about black communities in America.

Thus, it was a downright shock to many when Rock brought her out on stage following his monologue.

"The academy has taken steps to fix this problem and that is why it is my honour to introduce the director of our new minority outreach program," said Rock to the audience."Please welcome, Ms. Stacey Dash!"

The crowd fell almost silent as a smiling Dash said, "I cannot wait to help my people out. Happy Black History Month!"

A single clap was heard echoing throughout the auditorium.

Dash seemed to be in on the joke, writing in a blog post, "I'm sure many black people rolled their eyes," when she walked on stage, and reaffirming that she's not a "cookie cutter black."

U.S. Vice-President Joe Biden speaks out against sexual assault

Biden received a standing ovation from Hollywood's heavyweights ashe walked onstage to the John Williams-composedtheme song fromRaiders of the Lost Ark.

"I'm the least qualified man here tonight," he started."Despite significant progress over the last few years, too many woman and men on and off college campuses are still victims of sexual abuse."

Bidenwent on to introduceLady Gaga's performance of Best Original Song nominee Til It Happens To Youfrom the documentaryThe Hunting Ground.

But first, he asked "millions of Americans includingme, President Obama, the thousands of students I've met on college campuses and the artists here tonight" to join him in pledging to "change the culture."

"A pledge that says I will intervene in situations when consent cannot or has not been given. Let's change the culture. We must and we can change the culture. So that no abused woman or man, like the survivors you will see tonight, ever feel they ever have to ask themselves 'what did i do?' They did nothing wrong. I really mean this, take the pledge.
