Trend alert!

It seems to be very "in" to fall in love with your costar these days, and run off and get married without telling anyone.

Hot on the heels of the creepy Dexter siblings tying the knot, it has been revealed that Fringe costars, Mark Valley and Anna Torv are actually husband and wife!  According to Anna's rep, the couple got married in a "small, hush-hush" ceremony in December, after secretly dating for several months.

Well, I don't see what the big secret is all about but, congratulations anyway.
