Zoe Saldana will give birth in eight weeks.

The 'Guardians of the Galaxy' actress - who is expecting twin boys with husband Marco Perego - is ''feeling great'' but constantly hungry.

She said: ''I still have a ways to go. We have maybe eight more weeks or something. I feel great.

''I'm hungry all the time! I have to say, nothing makes me happier than to see a pregnant woman eat. Especially in LA!''

Tucking into a food tray provided by 'Late, Late Show' host Craig Ferguson, the 36-year-old beauty insisted she hadn't experienced any cravings during her pregnancy but had found food tastes better than ever.

She told the presenter: ''You'd be surprised -- I'm just hungry. It feels good. Food just tastes so delicious. It really does. It's really good. You trick yourself, working in Hollywood, going, 'That burger's disgusting. A burger's awful.'

''But now that [I'm] pregnant [I'm] like, 'I could eat all this --together -- at the same time.'

''Like, I could have the pickle with the donut and it would probably be life changing.''

And Zoe admits there is nothing she likes more than being told how ''sexy'' she looks with her growing baby bump.

She said: ''The best thing a pregnant woman can hear is the word 'sexy.' It's like, 'Oh, you think I'm sexy? Yes! I'm sexy.' You know?

''Usually I'm an activist and [a supporter of] women's rights. I'm like, 'Excuse me, do not objectify me!' or whatever, but now that I'm pregnant, I'm kind of itching for sexy compliments.''

While she isn't experiencing any unusual cravings, the 'Avatar' actress has developed an obsession with TV murder mysteries.

She said: ''In the middle of the night I don't wake up with cravings. I've been watching a lot of crime shows, though.

''I don't know why. Murder mysteries. I'm solving the case and it's like 2 o'clock in the morning because that's one of the gifts of being pregnant -- sometimes you just can't sleep.

''So, I find myself watching '48 Hours Mystery' or 'Dateline' with Lester Holt. My husband wakes up and I'm just like, 'He totally did it! She did it!' ''
