Jessica Simpson announced her engagement just days after Nick Lachey -- but we're told the timing is purely coincidental.

Sources close to the situation tell TooFab that even though the two have been together for only six months, Eric Johnson had been planning to pop the question to Jess for a while -- and it had nothing to do with Simpson's ex proposing to Vanessa Minnillo.

As we previously reported, Jessica has said she's "extremely happy" for Nick and Vanessa and wishes them "nothing but the best."
