Nicole Kidman is proving that age is just a number. The 50-year-old actress graced the cover of Love magazine in a sexy swimsuit and set the temperature soaring.

"She looks so damn good, like better than ever," a fan noted. Another commented, "Yessssss! Thank you for this . She gets better and better with age".

The actress who is always elegantly dressed at every red carpet event initially thought the photoshoot concept was crazy.

Nicole is quoted as saying on the magazine's Instagram page, "I thought about this shoot afterwards. I was like, "What was I doing? I lost my mind! How are the shots? Do they look crazy?"

The Lion actress was recently nominated for the best actress in a limited series or TV movie Emmy award, for playing Celeste Wright in HBO's Big Little Lies. The hit show scored 16 Emmy nominations, and Kidman will compete against her co-producer and co-star, Reese Witherspoon, in the same category at the award show to be held on 17 September.
