The 32-year-old 'Feeling Good' singer reached the milestone age two years ago, reported E! online.
"I love the thirties. I'm like, now I got the hang of it and being settled with myself and embracing it. I love the space that I'm in," Hudson said.
The actress recently unveiled the full music video for her collaboration with rapper TI, 'I Can't Describe (The Way I Feel)'.
'I Can't Describe (The Way I Feel)' was produced Pharrell Williams. The track is the first offering from Hudson's new album which is expected to be released later this year.
"I think it's more of a feeling, more than a genre, and I've had the pleasure of working with Pharrell (Williams) and Timbaland, and I love their process. They allow you to express yourself musically as an artist, as a writer, in every way. It's been a lot of fun," she added.
