Britney Spears spent another day poolside on Sunday, August 16, with her sons, Sean, 3, and Jayden, 2, at the Ritz Carlton on Marina Del Rey in California.

She looked gorgeous wearing a two toned green bikini, less so when she talked on her cell phone licking a heart lollipop with her tongue sticking out.

Britney's flirty bikini had a green and white pin stripe triangle top with center ring and halter tie on the neck, and a tattoo showing low rise bottom with metallic ring hardware.

Sean and Jayden, supporting recent buzz cuts, frolicked in the pool with sailboats as Britney watched.

On Saturday, the Womanizer star had flaunted her well toned body poolside wearing a pink bikini, once again with her toddlers.

Britney will kick off the second leg of her North American tour on August 20 at Hamilton, Ontario, Canada.

In November, Britney will jet off for her first ever tour Down Under with performances at Perth, Melbourne, Sydney and Brisbane.

Jordin Sparks will join Britney as a special guest on the second North American leg of the Circus tour.  "Britney's show is incredible and for me to be a part of it is a great opportunity," Sparks says.  Britney has been spotted visiting a recording studio lately, sparking speculation that she is already working on a Circus follow up.
