Steven Tyler knows a thing or two about life and love.

And the Aerosmith rocker, 63, says his fellow American Idol judge Jennifer Lopez is "as fine as can be" since her July split from hubby Marc Anthony after seven years of marriage.

"She's gorgeous. She's exuding this energy and this pulse from her heart," Tyler told Us Weekly Friday at the Andrew Charles launch at Macy's in NYC. "[She's] jumping into new ventures, be that her clothing line or the next [Idol] contestant, or a boyfriend or her babies."

"She's got this thing about her," he gushed. "You know, she still has Marc… They've just been married too long."

So why does Tyler think any guy would be lucky to be with the 42-year-old mother of 3-year-old twins Max and Emme? "She's a real something else," he said. "Behind all that, she's really a little baby girl… We all have a face but there's a little baby boy in me... She's very, very sweet."
