Hilary Duff isn't just a mom- she's a bounty hunter!
The Lizzie McGuire star was spotted carrying baby Luca in Studio City on Wednesday- carrying him to justice!
The lil' cowboy had used his bandana as a mask to rob the 3:10 Thomas The Tank Engine!
Ch-ch-check out the pics (below) to see Mom looking mighty pleased with herself after catching the elusive and adorable outlaw!
Gurl must have used those amazing leg muscles to head him off at the pass! LOLz!
