Natalie Portman is feeling glum about not being able to drink alcohol at the Golden Globes.

The award-winning star has been nominated for the Best Actress gong for her starring role in the biography movie 'Jackie', but will have to refrain from drinking at the glitzy ceremony on January 8 because she is pregnant with her second child.

Natalie, 35 - who already has a five-year-old son called Aleph with her husband Benjamin Millepied - said she would ''unfortunately not'' be able to drink at the awards ceremony.

The actress admitted she would much prefer to have a drink at the event, saying on 'The Late Late Show with James Corden': ''It certainly makes it a lot more fun.''

Earlier this month, Natalie - who won an Academy Award in 2011 for her starring role in 'Black Swan' - revealed she is craving pineapples and burritos during her pregnancy.

She shared: ''With (first child Aleph) it was very (different) ...

''I wanted cream puffs, anything dessert with cream in it, or just plain cream straight. This time it's, like, healthy - pineapple, cucumbers, burritos, which is maybe less healthy, but delicious.''

Natalie also admitted she can't wait to lose her baby weight.

She said: ''It does make you look forward to the day when you can just have your own body on the red carpet. It's weird because I'm a small person in general, so you show a lot faster and a lot more when you're small. Everyone thinks I'm about to pop and about to give birth any minute, and I have months to go.

''I went to the store the other day to buy water and the guy at the checkout counter was like, 'Almost, huh?' I was like, 'No! Not at all!''
