Serena Williams is unquestionably at the top of her game.

The 34-year-old tennis superstar covers the July issue of Glamour magazine, flaunting her killer physique in a sexy Wolford bodysuit. In a candid Q&A with the magazine, Williams addresses everything from her plan to have children in the future, sexism in sports, and those who blamed rapper Drake for her loss at the 2015 U.S. Open.

WATCH: Serena Williams Ate Her Dog's Gourmet Food Because It 'Looked Good,' Ran to the Toilet Two Hours Later

Williams -- who's rumored to be dating Alexis Ohanian, the co-founder of Reddit -- says she "definitely" wants to have kids, but only when she's more "mature."

"That's something I've always wanted since as long as I could remember," Williams stresses. And the older I get, the more I'm like, 'I'm too young!' I was just joking with [older sister] Venus about this yesterday and saying, 'I'm far too young!' Hopefully I'll be able to mature one of these days, get serious, and at least have them pretty fast."

Still, she's far from ready to retire from tennis and settle down. Williams is the defending Wimbledon champion, and is competing for another gold medal at this year's Summer Olympics in Rio de Janeiro.

"Who says that your thirties is when you're supposed to be done? I would like to know who made that rule!" she says. "I was talking to my mom one time, like, 'Gosh, I'm 30.' And she's like, 'In your thirties you’re even stronger than in your twenties.'I didn't believe her, but I have played better in my thirties. And I played pretty well in my twenties, don't get me wrong! But my consistency is better, my momentum is better, my wins are quicker."

Williams, who has faced both sexist and racist remarks throughout her career, also reiterates her stance on equal pay.

"These sports have a lot of work to do," Williams acknowledges. "And I really hope that I can be helpful in that journey because I do believe that women deserve the same pay. We work just as hard as men do. I've been working, playing tennis, since I was three years old. And to be paid less just because of my sex -- it doesn't seem fair."

"Will I have to explain to my daughter that her brother is gonna make more money doing the exact same job because he’s a man?" she adds. "If they both played sports since they were three years old, they both worked just as hard, but because he's a boy, they're gonna give him more money? Like, how am I gonna explain that to her? In tennis we've had great pioneers that paved the way -- including Venus, who fought so hard for Wimbledon to pay women the same prize money they pay men, and Billie Jean King, who is one of the main reasons Title IX exists."

Williams is also all about taking responsibility for herself. When the internet blamed her rumored fling, Drake, for her surprising U.S. Open loss to Roberta Vinci last year, she wasn't having it.

"I don't think that was fair," she comments. "I'm the one who's playing, who's making mistakes or making winners. I'm not one to blame anyone else for anything. And I don't think anyone else should either. I played a really good opponent that day. And I wasn't at my best."
