Reese Witherspoon gives an ad hoc seminar on safe sexting. Jennifer Aniston launches a PDA offensive with yet another male co-star. Kim Kardashian has wedding dress drama. Pippa Middleton never sweats. Monday gossip has sex tape remorse.

  • Reese Witherspoon subtly dissed Kim Kardashian and Blake Lively at last night's MTV Movie Awards:

  • I get it, girls, that it's cool to be a bad girl. But it is possible to make it in Hollywood without doing a reality show. When I came up in the business, if you made a sex tape, you were embarrassed and you hid it under your bed. And if you took naked pictures of yourself on your cellphone, you hide your face, people! Hide your face!

  • Sage advice for starlets and congressmen alike. Maybe New York lawmakers will hire her for that sexting reeducation program. Among those lauding Reese for this speech: Lindsay Lohan, for some confusing reason. [TMZ, Us, @LindsayLohan, photo via Getty]
  • People says Jessica Biel and Gerard Butler are having a "Cajun courtship." Their publicists and various gaydars say they're "just friends." [People]
  • Speaking of co-star relationships. Mere days after denying a relationship with Wanderlust co-star Justin Theroux, Jennifer Aniston went to an MTV Movie Awards afterparty and did this:

  • She adjusted [Justin's] tie, and he gave her a sweet kiss, sweetly rubbing her cheek. Wearing a black dress with a short leather jacket, she smiled ear-to-ear and leaned into her man, who rubbed her neck…. they exchanged kisses throughout the night. When it was time to leave, Theroux grabbed her booty and stole another kiss!
