The 33-year-old star and Speigel, were joined by their family and friend to celebrate their impending nuptials, reported E! Online.
"It was filled with close family and friends and the couple seemed really happy and in love.
"Miranda and Evan were very affectionate throughout the party. Everyone was celebrating and having a great time. Miranda and Evan get along with each other's friends perfectly," a source said.
The pair are set to tie the knot in 2017 and Kerr, who has five-year-old son Flynn with her ex-husband Orlando Bloom, previously opened up about Speigel's proposal, admitting it was a total surprise.
