James Corden has had some big names sit in his passenger seat during Justin Bieber sing old hits, talk underwear in 'Carpool Karaoke'">"Carpool Karaoke". First Jennifer Hudson, Mariah Carey, Justin Bieber and now Rod Stewart can be added to the list.

On Tuesday's episode of The Late Late Show with James Croden, the rocker joined the host during his daily commute to work and the two belted out a variety of classic jams.

The duo started off singing Stewart's hit, "The First Cut Is the Deepest." But they had a surprise guest when A$AP Rocky's hit "Everyday," which features Stewart and Miguel, came on the radio, the rapper appeared in the back seat.

"I don't know if I've ever felt as cool as I do in this moment in my life right now," Corden said. "I genuinely don't. To be in a car, in LA, with Rod Stewart and A$AP Rocky -- this is the greatest thing I've ever done."

But as soon as the song ended, A$AP no longer could be seen. "He's a lovely bloke, isn't he?" Stewart said of the rapper and Corden jokingly responded, "I don't know. I've never met him,"
