Shakira Makes Rare Red Carpet Appearance with Sons Milan and Sasha at Balloon World Cup: Photo

Shakira hit the red carpet with her family by her side.

On Thursday, the 44-year-old singer attended the Balloon World Cup in Barcelona with her partner, Gerard Piqué, and their two kids, Milan, 8, and Sasha, 6.

The family of four stopped by the red carpet to snap a few photos at the event, which was organized by Piqué and Spanish internet celebrity Ibai.

For the tournament, Shakira rocked a jungle-inspired tracksuit that was unzipped to reveal a red leopard-print bra. The young boys matched their mom in vibrant track jackets, Milan's embroidered with jaguars and Sasha's with a palm tree.

Earlier this month, the "Waka Waka" artist spoke about her children in an interview for the November cover of Cosmopolitan, opening up about parenting her young sons.

"My mind never stops," she told the magazine. "I dream about my kids. I worry about them constantly. I torture my poor husband. Well, he's not really my… I don't know what to call him!"

Shakira settled on calling Piqué her "baby daddy," explaining "I torture him about every issue I see with my kids."

"I'm a tiger mom and a helicopter mom and all these different moms," she joked to Cosmo.

The singer and the Spanish soccer star, 34, first met in 2010 and have never married. Last year, Shakira told 60 Minutes that marriage "scares" her, saying, "I don't want him [Piqué] to see me as the wife. I'd rather him see me as his girlfriend."
