The former "Pussycat Doll" and the "Apartment 23" actress grabbed a couple surf boards and hit the water at the Oakley Learn to Ride Surf event held at the Cabo Surf Hotel, luckily for onlookers, the duo took time to pose for few bathing suit clad action shots.
Krysten was joined by her "Hurt Locker" boyfriend, Brian Geraghty and took to Twitter after the event to gush, “Taught to surf by monster wave pro-surfer Ian Walsh! @oakleyaction omg!!! Are you kidding me!!”
Nicole - who wore a black and white gingham bikini - also tweeted after learning how to surf telling her fans, "Had the best day surfing with my girls in Cabo! Thanks @oakleyaction!!!!"
The "Killer Love" songstress was recently spotted celebrating her 34th birthday with beau Lewis Hamilton at London's Dstrkt nightclub until 3 a.m., which capped off her bday celebrations after partying in Vegas with her friends the weekend before.
