While she might be still coming to terms with it, singer and actress Katharine McPhee just turned the big 4-0! To celebrate, the star was joined by friends and family in abikini-clad boat ride that has us so jealous.

She shared some snippets of the celebration on Instagram, which included a picture of her showing off her toned physique in a light blue two-piece bikini and a straw hat. “It’s been such a magical week!” she wrote in the caption. “Thank you all for all the birthday love.”
