Seal: 'Heidi Klum Sings Really Well'

Seal stopped by "Extra" to chat with Mario Lopez about his seventh studio album, "Commitment," and to gush about his model wife Heidi Klum's vocal talent.

Heidi "sings really well, actually," Seal told Mario. The two even have a duet called "Wedding Song" on Seal's new album.

The soulful singer says the reason behind the title is that "it pretty much symbolizes my life in the last seven years, when I met my wife, and we have a family now."

Seal and Klum wed in 2005 and have three children; Henry, 5, Johan, nearly 4 and Lou, 1.
