Justin Bieber has been wearing some special “bling” lately in the form of a large, jewel-encrusted Stewie Griffin pendant around his neck. And this got the attention of ‘Family Guy’ creator Seth MacFarlane and Conan O’Brien on Monday’s ‘Conan.’

Of course, MacFarlane couldn’t just comment on the necklace himself. And that’s where the mischievous Stewie comes in.

MacFarlane, speaking in his Stewie voice, says he’s “never been more flattered” to have his likeness hang from the neck of the music superstar. “Stewie” also has some thoughts on this “Bieber Fever” that a lot of people seem to be coming down with these days. Check out the funny clip below.
