Nicole, who turned 50 on Tuesday, has previously opened up about how she plans to celebrate the landmark birthday. "[I want] to hang with my divine husband and my kids and my sister," she told E! News at The Beguiled premiere in Los Angeles, adding: "I've already been to Australia and saw my mom and it's too far for her to travel but my sister is coming over with all her children. She has six kids. I don't need any big parties; I just need my family around me. If I have my family around me I am happy."
