The star, who is due to give birth to a baby girl next month, relaxed with friends by the pool in a colourful swimsuit.
The 24-year-old is expecting with her fiancé, Ukranian boxer Wladimir Klitschko.
It's clear from the poolside pictures that she doesn't have long to go until welcoming her new arrival.
Signs point to a tall baby - although Hayden is just 5'2" in height, Wladimir is a staggering 6' 6".
The actress spoke about her growing bump in a recent interview, saying it was a difficult transition. "I'm 5 feet, 2 inches, and I started out at 106 pounds and guess how much I weigh now? Around 145 pounds... And the worst part is that my feet are still size five and they're going, 'What's going on with all this weight? They're about to snap from underneath me with the strain."
However she admitted she couldn't wait to meet her little one. "I’m so ready to hold my baby girl – I’m going to be a very hands-on mom."
Future new father Wladimir also spoke recently about his upcoming new arrival, saying he was excited for the big day. "When you're going to become a father or a parent, your life is going to change. So I look forward to having my life change for the good," he said.
We wish the expectant parents all the best!
