Victoria Beckham and her middle son Romeo Beckham attend day 2 at the US Open.

VICTORIA & ROMEO BECKHAM AT US OPEN

Romeo, 14, and younger brother Cruz Beckham, 12, often appear at tennis matches together, and Romeo is starting to look like he could be a star. His mother took her son out to enjoy some tennis at the professional level. They witnessed Madison Keys defeat Elise Mertens at the Billie Jean King National Tennis Center in Queens.

The former Spice Girl turned designer wore one of her eponymous designs – a sheer sky blue blouse and pleated skirt. Romeo dressed up in gray slacks, a button-down shirt, and a blazer. “Fun night out with my mum,” Romeo captioned his Instagram photo from the day.
