Rebel Wilson is celebrating Novak Djokovic’s success at the Australian Open with some funny social media posts of the pair.

The Pitch Perfect star, 43, who attended some of Sunday’s tennis action at Melbourne Park in Melbourne, appears to have met Djokovic, 36, after his win against Adrian Mannarino advanced him to the tournament’s quarterfinals.

On her Instagram grid, Wilson jokingly captioned a photo of herself with the Serbian tennis star “@djokernole 🎾🔥🎾💪🏻 Serb’s up!” In another photo of them posted on her Instagram Story, she tagged Djokovic and wrote “the champion” with muscle, flame and tennis emojis.

After Djokovic reshared her posts on his own Instagram Story, Wilson continued her praise, decorating a photo of them that he posted and jokingly adding a purple sticker that said “#1 Boyfriend.”

Of course, Wilson is spoken for and rang in 2024 with her fiancée, Ramona Agruma, and her 13-month-old daughter, Royce, as she shared in an Instagram post on New Year’s Day.

“2024’s already GREAT! 😘,” she captioned a carousel of photos of her family.

Later in the month, she got more vulnerable on Instagram, revealing that she’s gained back 30 pounds due to stress from working.

“It makes me feel bad about myself…it shouldn’t…but it does,” she confessed in the caption of the post. “I’m really proud of the work I’ve been doing on new movies and my memoir, it’s just been a LOT and I’ve lost focus on my healthy lifestyle.”

She then asked her followers if they could relate and updated the caption of the post later to tell everyone that their supportive and understanding words made her emotional.
