Spears posted the picture late on Monday evening, June 23, posing in the sunshine with her two boys. The "Work Bitch" singer smiles as she squints in the sun, looking fit in a pair of khaki shorts, a high-necked pink tank top, and a pair of open-toe wedge sandals.
"What's up summer!!!" Spears captioned the shot. "Where are my sunglasses when I need them? Lol."
The Las Vegas performer is flanked on either side by Sean Preston, 8, and Jayden James, 7, her two sons with ex-husband Kevin Federline. The boys look happy, grinning as they are ready for summer in shorts and T-shirts.
The young men may become older brothers to another child in the coming years. Spears, who is currently dating businessman David Lucado, said in an interview with InStyle for the January 2014 cover that she is hoping to have a daughter.
"I would like to be busy the first couple of years, but then I would really like to have another baby, a girl," she told the publication. "I think she would be like a mini-me. I think it’s going to be crazy. I’m not going to feel as alone in the world anymore. I’m going to feel like I have a second person, like, that’s me."
Spears fulfilled her wish to be "busy," with her ongoing Piece of Me Las Vegas residency at Planet Hollywood Resort & Casino. The gig is currently scheduled to run through February 2015, and may extend even further.
