Britney Spears is enjoying the best reviews of her career for Femme Fatale, her seventh studio album — and a happy domestic life with her beau Jason Trawick and sons Sean, 5, and Jayden, 4, with ex Kevin Federline.
"I feel like I'm drinking a tall glass of homemade sweet tea on a really hot, beautiful day," Spears, 29, tells the new Harper's Bazaar of life these days.
Might she continue that winning streak with another baby and marriage to Trawick?
"I've thought about both," Spears confesses. "So if the timing was right . . ."
Having bounced back from a rocky 2007 and 2008 (a custody battle with Federline and a short rehab stay), Spears looks back on how motherhood has transformed her.
"I think things through a little bit more, and I worry a lot. I'm more straightforward, and I speak up more than I did before," reveals the "Til the World Ends" singer. "When I was younger, I wouldn't speak up as much, but now that I'm a mom, things have changed."
Not too many folks can relate to Spears' teenaged super-duper-stardom — but Justin Bieber can.
"I think he's adorable," Spears gushed of the phenom, 17. "I just saw his movie, and I really didn't realize how big he was. He's enormous; he's just Mr. Man. A lot of the movie is really similar to what I did when i was starting out. I did a promo tour for a year, going into radio stations and all that. It was so cool to see our similarities."
