Love is clearly in the air at the Australian Open! One of Hollywood’s favorite couples, Nicole Kidman and Keith Urban, was spotted getting cozy at the Down Under tennis tournament on Thursday, January 24. The two were caught locking lips and hugging as they cheered on the competitors at the Women’s Semi-Final match in Melbourne.

The courtside cuties, both 51, who have been married since 2006, were all smiles as fans admired Keith and Nicole in the stands at the Rod Laver Arena while watching the intense match between Naomi Osaka and Karolina Plíšková.

Nicole even documented the fun occasion on social media. “I love the tennis! Thanks for having us #AusOpen,” the Big Little Lies actress enthusiastically wrote in the caption of a selfie she shared on Instagram.

Earlier this month, Nicole candidly opened up about the moment she realized her “Blue Ain’t Your Color” singer hubby was the one for her. “It was my [38th] birthday, and he stood outside with gardenias at 5:00 a.m. on my stoop in New York,” the Destroyer actress told People. “That is when I went, ‘This is the man I hope I get to marry.'”

Keith then took her to Woodstock, New York to the site of the famed 1969 music festival on a motorcycle for a getaway — and she’s been hooked ever since! “It was pretty intense,” Nicole recalled. “I believed by that point he was the love of my life. Maybe that’s because I am deeply romantic, or I’m an actress, or I have a strong faith as well, but I just believed, ‘Oh, okay, here he is.‘” Aww!
