Stephen Colletti and Lo Bosworth swung by the KIIS FM studios for a little chat with Ryan Seacrest yesterday morning. While Ryan was busy making it glaringly clear that he’s a woman-loving playa — and singing the praises of such a “pretty show” as The Hills – Lo and Stephen played it diplomatic, refusing to spill major secrets or talk too much trash. But when Spencer phoned in for a little impromptu provocation, the temperature rose. Listen for yourself here as he opens up a fiery vault of dramarama — refusing to let the LC sex tape rumors die. Lo responds with some choice words about Spencer and his mama.

There are some real cringe-worthy moments, although I personally felt most uncomfortable when Seacrest asked Stephen what he’s “packin’”.
