Tiffani Thiessen and her daughter, Harper Smith, shared a slew of adorable moments at the grand opening of Bowlero bowling alley in LA's Woodland Hills on Saturday afternoon. The mother-daughter duo traded in their flats for a pair of bowling shoes, and Tiffani happily looked on while Harper excitedly went for a strike. The former Saved by the Bell actress was even spotted giving her mini me a few pointers and snapping photos on her cell phone. Missing from the fun, though, was Tiffani's husband, Brady Smith, and their nearly 1-year-old son, Holt Smith, whom the actress often photographs — you can catch her shared pics on Instagram.
