Jessica Simpson purse cloak engaged boots jeans holding hands

Jessica Simpson's fashion empire is expected to earn $1 billion this year AND the former singer is engaged to be married again - now that's two causes to celebrate!

Simpson and Johnson visited the Whisky Mist in London Sunday night (and she left looking like a hot mess), and last night the two traveled to the Plaza Athenee hotel in Paris. Nothing like a little European vacay to put a smile on the starlet's face!

Meanwhile, Jess is still considered to be the top contender as a judge of the new X Factor - think she has what it takes to sit next to Simon Cowell? If Paula Abdul could do it, so can Jessica Simpson!
