Telling Ryan Seacrest on his KIIS-FM radio show that she is "very with" the Twilight hunk, McCord, 23, says there's never a dull moment for the pair.
"I think he's crazy in a different way [than me]," she says. "He's just a wild child."
Prompted by Seacrest to admit she "wears the pants" in the relationship, McCord, 23, would only concede that the two "share the control."
And though the two recently celebrated McCord's 23rd birthday together, with a dinner in Los Angeles, Lutz is currently on vacation without his girlfriend.
Where is he?
"He's in Israel," she says. "Before the 75th Twilight [film] comes out, he has five minutes of a break."
