It's been nearly 30 years since Paulina Porizkova graced the cover of the Sports Illustrated Swimsuit Issue, and judging by these recent photos, she still could be featured in the popular publication!

The 48-year-old tweeted a pic of herself stretching out in the pool with the caption, "Doing the siren for my hubby in the Raleigh pool."

Her hubby is Ric Ocasek, the frontman of the rock band The Cars. They have two kids -- but you couldn't tell that from her taut tummy.

Paulina is only one of four models to have back-to-back S.I. covers (1984-1985). Christie Brinkley (1979-1981), Elle Macpherson (1986-1988), and most recently Kate Upton (2011-2012) are the others.
