After-Bash! 2015 Oscar After Party: Inside The Star Studded Festivities -- Plus, All The Drama!

After the party, it's time for the after-party, which is exactly where Hollywood A-listers flocked, arriving at the Wallis Annenberg Center for Vanity Fair's annual Oscars party. Starting us off in style, Reese Witherspoon looking like a dreamboat.

Jennifer Aniston and fiancé Justin Theroux were too cute! Clearly more in love than ever, the couple playfully posed for cameras as they entered the celebrity bash.

Speaking of love, have you seen Sofia Vergara's ring?! She and Joe Manganiello are so attractive together it hurts…of course you also can't look away.

Nearby, Emma Stone got the giggles with Oscar winner Julianne Moore.

Winner for Best Actor, Eddie Redmayne flashed a sweet smile as he held his hefty statue on display.

Julianne Moore seems to be cracking everyone up tonight! The starlet shared a laugh with friend and Crazy Stupid Love co-star, Steve Carell.

Oh, Miley. Nothing more needs to be said except, perhaps, where's boytoy Patrick Schwarzenegger?

Benedict Cumberbatch and pregnant wife Sophie Hunter glowed as they posed for cameras. They're definitely in the honeymoon phase!

She's still Queen Bey, even in the movie business. Beyoncé stole the show for the Vainty Fair after party, looking sleek in an all-white outfit.

Then, there was John Travolta sporting a…choker? Looks like the actor opted for bling over a bowtie.

Staying true to his colorful style, ombre-fashioned Jared Leto

'wore a powder blue suit with retro white shoes.

Meanwhile, Sia donned her usual iconic wig.

Selena Gomez didn't look particularly happy about attending the bash, maybe because ex Justin Bieber seems to be awfully close with Hailey Baldwin these days.

Solange Knowles matched her big sis in a bright white get-up.

White seems to be a trend for the pop princesses this year! Christina Aguilera struck a fierce pose in her white patterned gown.

Lady Gaga dressed down (surprising, we know) from her Oscar ceremony gown and sported a black gown – and her engagement ring! – for the bash.

Jay Z donned his usual white coat and luckily didn't start any drama with Solange this year.

Meanwhile, Heidi Klum sported a daring outfit. The mother-of-four wore a sparkling Versace gown that exposed plenty of side boob. Her very visible hips suggest that the model also ditched her drawers for the evening.

J. Lo's outfit comes as less of a surprise. The singer-actress has always enjoyed showing off her toned figure.

To top it off, Sasha Baron Cohen and pregnant wife Isla Fisher keep their cool while posing for cameras.
