- Creator Backlash:
- She has a low opinion of Knocked Up, due to what she felt was a one-dimensional portrayal of the genders: women as joyless nagging shrews and men as immature brats who avoid or resent their responsibilities in life.
- She also famously criticized the writing of her character, Izzy, in Grey's Anatomy. It got her a lot of flack from the creator of the show.
- Creator Couple: She's married to pop singer Josh Kelley (who is also the brother of Lady Antebellum co-lead singer Charles Kelley).
- Dyeing for Your Art: Famously blonde, she dyed her hair brown during production for One for the Money, but ultimately wore a brunette wig because her own hair lacked the curliness and volume Stephanie Plum's hair called for.

- Statuesque Stunner: She's 5'9 and a successful model.
- Typecasting: She usually plays a high maintenance woman who, while successful in her career, has a poor love life.
