Like mother, like daughter? Not so much.
While Liv Tyler's model mama Bebe Buell bared all for breast cancer awareness, her daughter and mother Dorothea Johnson took a more demure approach.
As Liv posed for pics with mom and grandma, she quipped, "TMZ -- aren't you the naughtiest website of all time?" And Mom Bebe mimicked TMZ's video clip intro music. "Boom, boom, boom!"
She's a fan!
