Ellen Degeneres didn't get a lot of sleep after the Oscars last night (02.03.14).

The talk show star hosted the prestigious Hollywood event live until late last night, then let her hair down by partying afterward, leaving her feeling worse for wear this morning.

She wrote on Twitter after the show: ''Thanks for watching and tweeting! Now I need to meet with my friend, Margarita. See you tomorrow for my live show! #Oscars''

Today (03.03.14) she followed up with a tweet saying: ''Gopd mrorining! It'sd time to do a live OSxar show. Didn't get much slep but whoneds it? (sic)''

Ellen then posted a picture of her holding cold cans of fizzy drink under her eyes, with another caption reading: ''Getting ready for my live show. #Tired (sic)''

Ellen's hosting was well received and her jokes with the audience and actions including ordering pizza halfway through went down well.

However, her most successful move of the night was to hand her phone to Bradley Cooper to take a multi-celebrity 'selfie' picture and post it on Twitter, which quickly went on to become the most successful tweet in history, gaining over two million retweets by this morning.

As well as Ellen and Bradley, Jennifer Lawrence, Jared Leto, Meryl Streep, Julia Roberts, Kevin Spacey, Brad Pitt, Angelina Jolie, Lupita Nyong'o and her brother Peter all crammed into the photograph and its popularity resulted in technical difficulties for Twitter.

Ellen later told the audience at Hollywood's Dolby Theatre: ''So this is true. We just crashed Twitter. We got an email from Twitter, and we crashed and broke Twitter. We have made history. See, Meryl, what we did? You and I? It's amazing, we really just made history. It's fantastic.''
