Katie Holmes and Suri Cruise visited a track field in Boston, Massachusetts yet again today (October 13) — but this time the workout was for one!

After putting her hair in pigtails and strapping on a rare pair of running shoes for their inaugural mother-daughter day of track and field, three-year-old Suri was back in her trademark dress-sparkly red shoe combo this afternoon as she watched on (albeit impatiently) as Katie ran laps while jamming out to her iPod.

Meanwhile, a pulicist for Tom Cruise have put the kibosh on reports that young Suri has amassed a wardrobe valued at more than $3.5 million.

Rep Jeff Raymond says: “This report is ridiculous, and simply not true.”

That said, celeb stylists continue to weigh in on Suri’s fashion icon status. Phillip Bloch tells ABC News: “You don’t hear of Lourdes [Madonna's daughter] being dressed like that or Jennifer Garner and Ben Affleck’s kids. You see Maddox [Jolie-Pitt] wearing the same T-shirts. They are kids. Most celebrities want their kids sheltered from this kind of existence. They want them shielded from the media. But it’s like they [Cruise and Holmes] are pimping her by putting her so out there.”
