Note to Rob Lowe: Stop looking so damn healthy. Signed: The powers that be at ABC.Seriously, Brothers & Sisters' star Rob Lowe has been ordered to stop tanning. Apparently, the actor just looks too good -- bronze and healthy and full of that Kennedy-style of vigor for the role he's playing. ABC brass, the president of the network no less, has told him to stay out of the sun. According to Lowe, he was warned that he is getting too dark and has to mend his ways now.
