The pitter patter of little feet for T.R. and Mark.

Out Grey's Anatomy star T.R. Knight may be ready to take a huge step with his boyfriend, the ... slightly younger UCLA student Mark Cornelson. Or it could be just tabloid innuendo.

T.R. tells OK! Magazine that he's looking forward to raising children in the future:

“I wouldn’t rule [adoption] out at all. I think it would be adopting versus any other route. But yeah. I mean, there are a lot of kids who need homes.”

Of course, he doesn't say when or even if he'll be doing it, but the article makes it seems like he's ready to hit up Angelina Jolie for one of her spares.

According to BGAY.COM,the couple may be hearing wedding bells soon:

T.R. Knight will join the Matthew Shepard Foundation to help kick off National Gay-Pride month with a symbolic dusk commitment ceremony at the famed West Hollywood hotspot, The Abbey, on June 4, 2008. Couples from around the nation will “tie the knot” in an event officiated by the Mayor of West Hollywood and rumors has it T.R. and Mark will be among the marrying couples.

Again, this conjecture travels and warps quickly. I guarantee that what started as T.R. to attend charity function with boyfriend will eventually morph into T.R. and boyfriend to marry & adopt Cambodian conjoined twins.
