The "Aliens In the Attic" actress was joined by gal pal Casey Weinart, with the pair looking in no mood to be photographed as they headed to the car following the midday sweat session.
Stepping out for dinner later the same evening, Tizzie tweeted of her north of the border celeb sighting, writing, “Just ran into Katie Holmes at a restaraunt…..wow she is one of the nicest people! made my day :)”
Meanwhile, Ashley also voiced her hopes for plenty of viewers for tonight's all-new episode of "Hellcats" - which airs tonight (February 9) at 9/8c on The CW.
She tweeted, "Hope everyone is gonna watch #hellcats!!! Awesome episode tonight"A synopsis of the latest installment via the show's website tells: "Savannah (Ashley Tisdale) and Alice (Heather Hemmens) throw a toga party at Lancer, hoping the festivities will take their minds off the fact that the Hellcats might lose their funding. Marti (Aly Michalka), Vanessa (Sharon Leal) and Julian (Gale Harold) come up with a plan that just may get Travis (guest star Ben Cotton) released from jail and save the Hellcats."
