She-Hulk told Harper's Bazaar that she's in no rush to marry Justin Timberlake or anyone else:
The actual idea of signing those papers and doing all this stuff ... I’ve never been someone who’s like, "I have to, have to, have to have it."
Biel also talks about her struggles to fit in in Hollywood:
I felt for a long time that I wasn’t ballsy enough. Not cool enough. Not strong enough. Too much of a pushover.
That explains the bodybuilder physique and the pitbulls. This chick has the psyche of the kid in the Charles Atlas ads. Someone kicked sand in her face. She probably practices with nunchucks a lot. She's a weird one, anyhow.
