Despite reports yesterday that claimed Reese Witherspoon and Jake Gyllenhaal, who are already shacked up together, were engaged and planning on getting married by the end of this year, Jake's rep issued a firm denial this morning.

His rep told X17online that the rumors are "not true" and that Reese & Jake are "not engaged."

But we can't help but think it's only a matter of time before they are!
