It seems that married life is agreeing with Alicia Keys
"It's so fly," the singer tells PEOPLE. "There's something great about feeling at peace and ease with your partner and knowing you understand each other. I really enjoy that friendship."
Keys, 31, who will celebrate her one-year anniversary with producer husband
Swizz Beatz on July 31, adds that being like-minded with her mate helps keep things harmonious.
"There are so many similarities between us, it's just mind-blowing," she says of Beatz, 32 (with whom she welcomed a son
named Egypt last fall). "It's really cool to have met my equal."
In fact, the two are so in sync that Keys even trusts Beatz (real name: Kaseem Dean) with helping her pick outfits for public appearances.
"I can say, 'I'm not sure about this look for the BET Awards. What do you think?' and I know that he will honestly tell me exactly what's up," she says.
The singer, who is also celebrating a professional anniversary – with the re-release her 2001 debut album, Songs in A Minor
– says her wedding day tops the list of her favorite moments over a very eventful decade.
"When I walked down [the aisle] and saw him, I could barely hold myself together," she says. "It was so beautiful – just about he and I and our love. The wedding was one of the best days of my life."
