Gal, 32, captioned the snap: "Read my lips [red lips emoji]. Tonight is the night! Good luck to all the nominees! I'm so excited to be up on stage to honor tonight's winners.

Meanwhile, Ansel previously admitted that he uses his social media accounts to further his acting career.
The 'Baby Driver' star also revealed he hopes to be a positive influence on young people through his online presence.
He said: "I mean, that's why I'm on social media, that's why I am active on the internet because I think it's beneficial to someone's career.
"But also I have an audience and I think I have taken this role, whether I like it or not, as an influencer and I want to be a positive influencer. I want to encourage people. One of the things I do encourage people is that that internet is a place where we should share our ideas and be positive, not negative."
