Backstage Report: Stephen Colbert Down With Lady Gaga

All the dish from backstage at 52nd Annual Grammy Awards

Stephen Colbert is doing show tunes. Joe Jonas is rocking specs. And Lady Gaga is making her presence felt.

Here's what shaking backstage at the 52nd Annual Grammy Awards:

5 p.m.: The Lady Gaga show is making our windows rattle. Non-euphemistically.

• Best Comedy Album winner Stephen Colbert was "born for the Grammys." So, what else is new? How about him breaking into Barbra Streisand? "Don't tell me how to live…!" he offers in his lovely singing voice.

• Colbert's Justin Timberlake-dissing show-opening monologue seemed to quiet the Staples Center like the Michael Jackson memorial. Nope, it ain't easy to make the Grammys laugh. "It's not exactly a 500-seat comedy club out there," Colbert says.

• Et tu, Colbert? Yup, the faux right-winger has been seduced by Lady Gaga. "She's fantastic," he says. "They're going to spray her with glue, and send her through a Build-a-Bear Workshop."

• Even more surprising, the faux right-winger's gone soft on John Edwards. "I'd love to have the senator on," Colbert says of his Comedy Central show. "I'm sure he could use a laugh. "

• Keith Urban presented right after Pink's "Glitter in the Air" show-stopper. So, did the country winner have a good seat for the whirling, twirling spectacle? Nope. "I saw it on television."

• Jason Mraz is chillin'. So, what else is new? "They're my first two," Mraz informs us, toting the pair of Grammys he won for his duet with Colbie Caillat, "Lucky." "They're fantastic. Do they play on MP3s?"

• That barefooted Jason Mraz-Jack Johnson-Dave Matthews sketch on Saturday Night Live made an impression. We need to know if Mraz is wearing shoes. We can't see from our seat, so we get up…only to find the view of his feet covered by ferns. He walks offstage…only to find the view of his feet covered by a black curtain. We wait patiently…until…he makes it to the exit…and see…yes, he's wearing shoes!

• India.Arie ("Pearls") looks like a million sparkly bucks. Credit her designer. "You know my mom made this," she tells us.

• Whatever happened to sex, drugs and hotel-trashing rock 'n' roll? India.Arie's wearing Mother. Colbie Caillat's accompanying Father. "I have my dad here with me as my date," Caillat tells us.

• Spotted: Joe Jonas adjusting his neck during his and his brothers' official Grammy-night portrait sitting. Either it's been a long night, or those new glasses of his are giving him a headache.
