It seems like only yesterday Sarah Michelle Gellar and Selma Blair were swapping spit as teenagers in "Cruel Intentions" ... but now they're full blown moms!
The two were spotted out over the weekend -- sorry, not together -- where they posed for photos with their adorable children.
The 36-year-old "Buffy the Vampire Slayer" star took 3-year-old daughter Charlotte to Ringling Bros. and Barnum & Bailey Circus' "Built to Amaze" show at the Staples Center on Sunday. Doesn't little Charlotte look just like her famous daddy, Freddie Prinze Jr.?
And Selma, 41, took son Arthur to the Farmer's Market in Studio City yesterday, where she showed off her new blond 'do. Her little guy turns 2-years-old on the 25th -- he's getting so big!
Check out the gallery above to see even more celeb kids -- including SMG's former "Buffy" costar Alyson Hannigan's two cuties.
