SPOILER ALERT: GET READY FOR THE JUICIEST CELEBRITY NEWS OF THE WEEK!

In a shocking turn of events, comedian John Mulaney celebrated his 43rd birthday in style by attending the US Open Tennis Championships in Flushing, NY with his stunning second wife, Olivia Munn. The Chicago-born funnyman and his 45-year-old breast cancer survivor wife were spotted jumping to their feet at the USTA Billie Jean King National Tennis Center to cheer on Coco Gauff's triumphant win during day three of the tournament.

But what's even more fascinating is that John and Olivia, who just celebrated their first wedding anniversary over the Fourth of July weekend, have been making headlines for all the right reasons. Sources close to the couple reveal that Olivia has been keeping a watchful eye on her husband's recovery, administering random drug tests to ensure he stays on track following his highly publicized rehab stint in December 2020.

John's struggles with addiction have been well-documented, but it seems like he's made significant progress under Olivia's loving care. And let's be real, who wouldn't want to wake up next to this beautiful woman every morning? Olivia, who's known for her stunning looks and sassiness, looked absolutely leggy in a sleeveless beige mini-dress that showcased her toned physique.

But before their whirlwind romance began, John was married to Anna Marie Tendler for six years. The couple met at Seth Meyer's wedding in 2013, but it wasn't until they reconnected "at church in LA" in February 2021 that the sparks really flew. However, things took a dramatic turn when Olivia revealed that she had checked herself into a psychiatric hospital for self-harm and depression just months after meeting John.

Anna Marie filed for divorce from John in January 2022, citing irreconcilable differences. But it seems like John has moved on and is loving life with his new wife. After all, who wouldn't want to share their life with a breast cancer survivor who's as beautiful inside and out as Olivia?
