Fergie has certainly been working on her fitness.

The 42-year-old singer showed off her "lovely lady lumps" in a black string bikini while vacationing in Hawaii over the weekend, and paired her sexy style with several silver rings, aviator sunglasses and adorable pigtails.

Fergie may have a little more time on her hands this summer after it was revealed in June that she was no longer a member of the Black Eyed Peas. A source close to the Peas told ET at the time that the triple-threat star still has the support of her former bandmates as she pursues other music endeavors. "Fergie is still in the family but is focusing on her solo project," the source said. "She is like a sister to them. They fully support her."

This isn't the first time this year that the "M.I.L.F." musician has inspired some serious swimsuit envy while in Hawaii. In January, she jetted off to the tropical paradise and was spotted running down the beach in yet another string bikini.
