Former chart-topper Ashlee Simpson and Hunger Games star Evan Ross (who is also the son of Diana Ross) have tied the knot. The couple, who got engaged back in January after a year of dating, got married at his mother’s estate on Sunday. According to Us Weekly, Ashlee wore a pearl-embellished long-sleeved gown which she finished off with Neil Lane rubies, diamonds and a tiara. Evan opted for a black velvet tuxedo with a white silk trim. While it was his first trip down the aisle, she was previously married to Fall Out Boy’s Pete Wentz with whom she has a five-year-old son called Bronx. Ashlee and Evan tied the knot over the weekend.
