Pink, whom Us Weekly reported last week is 12-weeks pregnant, took a dip over the weekend.
Wearing a black bikini, the mom-to-be, 31, was all smiles as she enjoyed a relaxing day in the water in the L.A.-area.
Though she has yet to confirm the news, one of her pals let it slip on Twitter last week.
On her Twitter page, Good Day L.A. co-host Jillian Barberie Reynolds wrote: "Congrats on baby!! Ps. You know your man whispered it to us at dinner." Realizing Pink hasn't wanted to make the news public, she quickly backtracked: "Hubby says that I must have been tipsy that night cuz that's not what Carey said!!
