The loved-up pair joined David, seven-year-old Harper and their pet puppy Olive for a day out on Sunday, making the most of the good weather for a spot of family time.
Former England ace David shared a sweet snap of Brooklyn, 20, and Cross, 21, cosied up on one of the motors, adding some animated red hearts.
David couldn’t resist taking a selfie with the lovers as he made sure to photobomb the unsuspecting couple by sneaking into the side of the shot.
David also shared pictures of Harper riding with Olive.
The youngest of the famous family grinned as her dad captioned the shot: “Smile girls.”
Brooklyn and Cross were first spotted out and about together in December at the British Fashion Awards in London. They confirmed their romance a few weeks later with sweet social media posts.
In February, Brooklyn declared himself “the luckiest man in the world” after he whisked Cross away to Paris to celebrate Valentine’s Day. The pair posted a series of loved-up snaps in front of famous Parisian landmarks.
His parents, David and Victoria, are celebrating 20 years of marriage this July but plan to keep celebrations “low key”, according to the fashion designer.
“David is such a great husband, such a great dad and the most incredible business partner that anybody could ever want,” she told Entertainment Tonight. “He really supports me in what I do.
“[But] I don’t think [we’ll do anything big]. We’ll probably just celebrate with the kids.”
Victoria and David also share Romeo, 16, and 14-year-old Cruz. They married in 1999 at Luttrellstown Castle in a lavish ceremony.
