Here’s a great photo tweeted out by supermodel Cheryl Tiegs featuring Kate Upton and Kathy Ireland on the red carpet for a Sports Illustrated event. Both of them are showing off some impressive cleavage with their low-cut dresses. That’s become pretty common for Kate but it’s always nice to have Kathy Ireland back in the mix. It’s also great to see today’s SI supermodels hanging out with classic models as well. Very nice!
