Ciara Is a Proud Sister-in-Law Posing With Russell's Sister Anna in a Snap with a Sweet Caption

Ciara took to Instagram to share a photo with her sister-in-law Anna Wilson. The "Goodies" hitmaker penned a sweet message to celebrate her husband, Russell's lookalike sibling, for an incredible victory.

It seems athleticism runs in the family of NFL player Russell Wilson, whose younger sister, Anna Wilson recently took home the championship at the Women's NCAA Tournament final.

On April 5, Anna, who was named the Pac-12 Co-Defensive Player of the Year, and the Standford Cardinal, beat the Arizona Wildcats, and both her brother Russell and his wife, Ciara, couldn't be more proud.

Russell and Ciara expressed their pride with sweet messages on social media. Ciara took to Instagram to celebrate Anna's victory with a photo of the pair posing together on a quiet street curb. She captioned:

"The Champ is Here @awilly03! Love you! You inspire me ❤️ #NY."

In the snapshot, Ciara and Anna looked chic in their stylish outfits. Anna donned a white top paired with black wide-leg trousers which she topped with a white jacket, while Ciara opted for a more bold look.

The "I Bet" hitmaker's ensemble featured black leather pants and ankle boots worn with a faux fur sweatshirt from The North Face x Gucci collection. She accessorized with multiple bracelets and chic sunglasses.

Ciara revealed that she and Russell challenged themselves to remain celibate.

In the post, Ciara and Anna's body language showed how much they adore each other. After all, Ciara has been a part of the Wilson family since 2015 when she met and started dating Russell.

Ciara and the Seattle Seahawks quarterback recently celebrated six years of love with romantic messages on Instagram. Although they fell in love immediately, they only tied the knot in 2016 after taking time to understand each other deeply.

During the early days of their courtship, Ciara revealed that she and Russell challenged themselves to

. She told CBS News they wanted to build an emotional foundation without the distraction of a sexual relationship.

Ciara also opened up about her son, Future Zahir Wilburn, who she shares with her ex-fiancé, Nayvadius "Future" Wilburn. At the time, she was facing backlash for allowing her son to build a relationship with Russell so early into the relationship.

Fortunately, Ciara and Russell's love was meant to last, and they are still happily married. The couple has since added to their family with two beautiful kids, Sienna, 3, and baby Win, eight months.

Since welcoming her third child, Ciara, 35, has been open about motherhood and her weight loss journey. However, less than a year postpartum, the "Body Party" songstress is already looking fabulous and rocking sexy swimsuits on her Instagram page.
