David and Victoria Beckham took to social media to share some adorable photos of their daughter Harper along with sweet messages to mark her fifth birthday on Sunday, less than a week after the couple celebrated their 17th wedding anniversary.

The fashion designer posted a photo on Instagram that shows the special bond that she has with her youngest child and only daughter Harper. In the photo, the mother and daughter can be seen giving each other a kiss while donning sunglasses in a swimming pool.

"Happy Birthday baby girl We all love you so much X @davidbeckham @brooklynbeckham kisses from mummy X," the 42-year-old mother wrote.

David also shared a black-and-white photo of Harper giving her father a kiss on the cheeks.

"Happy birthday to my Pretty Lady In 5 years baby Harper has brought so much love into our family ... Such a special girl in so many different ways we are so lucky to spend each day with such a beautiful soul ... We adore you baby girl happy birthday love Daddy ❤️ @victoriabeckham," David wrote on Instagram.

The former member of Spice Girls and her daughter enjoy plenty of girl time.

"I'm very girly and I love nails. Harper and I will often have nail afternoons and when we're in L.A., we even send our dog to a nail spa called the Beauty Spot for a paw-pedicure," Victoria told Vogue magazine in their January 2015 issue, according to E!Online.

In September 2015, the former football player told Entertainment Tonight that he places fewer restrictions on his daughter than his sons: Brooklyn Beckham, 17, Romeo Beckham, 13, and Cruz Beckham, 11.

"I have no power with that little girl -- no power whatsoever," Beckham said. "I love all my children, of course, equally but I'm definitely stricter with the boys than I am Harper, which gets me in trouble with my wife of course."
