Jessica Alba and her family celebrate her father-in-law Michael Warren’s 75th birthday

She was moved to tears back in September when she realized that her oldest daughter was officially taller than she was.

And the height difference was more apparent than ever as Jessica Alba stood next to her 12-year-old daughter Honor while out in Beverly Hills on Sunday.

The 39-year-old actress and her daughter wore complementary shirts while joining the rest of their family to celebrate her father-in-law Michael Warren’ belated 75th birthday.

Party time: Jessica Alba, 39, was towered over by her oldest daughter Honor, 12, as they joined the rest of their family to celebrate her father-in-law Michael Warren’s 75th birthday in Beverly Hills on Sunday

Jessica and the rest of her family were dressed casually for a fun afternoon.

Like most of the other guests, she wore a white T-shirt that had been printed with an old photo of her father-in-law Michael, a star UCLA basketball player who went on to be an actor best known for playing Officer Bobby Hill on Hill Street Blues. 

Jessica’s photo featured a black-and-white photo of her father-in-law wearing his Hill Street Blues jacket in the 1980s. 

She had a light brown hoodie wrapped around her waist and wore a matching pair of brown sweatpants.
