Dudes and Dates: Hilary Duff is all smiles as she teaches son wheelbarrow in school

She's a doting mom to six-year-old son Luca.

And on Friday Hilary Duff spent the evening with the lad she shares with ex-husband Mike Comrie at an event at his school in Los Angeles.

The 30-year-old Younger star shared a cute snap of them together on the playing field, captioned: 'Last night was "dudes&dates" at Luca’s school!

'Lot of competition lol the boys crushed the moms at dodge ball. I taught Luca the wheel barrel...check out that concentration lol.'
