Reese Witherspoon and Jake Gyllenhaal have been dating for more than two years, and now the Legally Blonde star wants to make it legal. "Reese's best friend, Heather Whitney [co-owner of the LA clothing store Poppy], just got engaged," reveals an insider. "She's got Reese thinking! People around her have been speculating that she and Jake are getting closer and closer to the altar, and Heather's engagement only puts that much more pressure on them." In fact, Reese and Jake might already be secretly engaged, the insider believes: "At least they're discussing it. Close friends shrug and say 'I don't know anything' when you can tell they know something," says the insider. "Everyone in their circle is talking about it. It's like any other relationship -- the marriage issue has finally caught up with them."
