Olivia Munn and John Mulaney both became first-time parents with the arrival of their son Malcolm in November 2021. Beach mode: Olivia Munn, 43, jokingly admitted she and partner John Mulaney, 40, struggled to put sunscreen on to their 20-month-old son Malcolm during a family beach day In the first series of four photos, Munn can be seen applying the sunscreen all over Malcom, less than 100 feet from the incoming weaves from the ocean. And we didn’t even do a good job,' the Iron Man 2 star joked in the caption under a series on snaps from the day Beach day: The actress was dressed in white shorts and a matching sheer top over her bikini while trying to apply the lotion Sweet: Munn did her best to shield her baby boy from sun exposure as she continued to apply the lotion Difficult: However she admitted it was an 'incredibly difficult' task Admission: Munn admitted she's 'not very good' at applying sunscreen lotion Promo mode: Munn later slipped into promo mode by taking pride in having her family drink Poppi, which contains apple cider vinegar that gives the drink all kinds of prebiotic benefits Those prebiotics are fibers that feed the natural probiotics in your digestive system, that in turn boosts the body's natural immunity. Loves it: The former Newsroom star boasted how 'John loves the new cola @drinkpoppi' in a photo of the former SNL writer lounging on the beach underneath an umbrella Fun in the sun: After wiping off some of the lotion, Malcolm was finally able to go play Grateful dad: Mulaney thanked Munn for making him a dad in a Father's Day post this past June The comedian was seen shirtless holding his son while sitting in an inflatable floating chair in the water, with Munn at his side, while seemingly floating down a lazy river. He also shared a video of him holding Malcolm, while Munn asked him to say 'Happy Father's Day,' which Mulaney captioned, 'God**mn I’m a lucky guy.'
