Her children are no longer in diapers, but Gloria Estefan is still on baby duty.
The singer and her husband of 34 years, Emilio, keep busy tending to their brood: English bulldogs Isaac, Biggie and Noelle, and Chihuahua Lulu.
"They're my babies," Estefan tells PEOPLE in the latest issue. Because they have such a prized place in her heart, the furry foursome have full run of the Estefans' 15,000-sq.-ft. Miami Beach waterfront estate.
"This house has a lot of space for entertaining," she says of the home, where she recently hosted Tom Cruise
and Julianne Hough
during the wrap party for Rock of Ages
Estefan posed with her babies on the sprawling property, looking glamorous with Lulu in her arm and the bulldogs at her feet. "We didn't even have to wrangle them, they just sat wherever I happened to be!" she told a fan on Twitter
The reason Lulu got the place of honor with Estefan that day? "Lulu's put on a bit of weight and likes to be carried around all day!" she wrote
. "My shoulder has felt it…lol!"
