Happy 17th anniversary, Ryan Seacrest! Seacrest celebrated 17 years on-air on 102.7 KIIS FM by reminiscing with former co-host Ellen K.
Ellen, who hosts KOST 103.5, joined Seacrest via Zoom and took a trip down memory lane, recalling their first-ever guests Hilary Duff and Britney Spears back in 2004.
Plus, do you remember when Seacrest was in Shrek 2?
