Is there anything like partying with your mom in Las Vegas?

We’d have to ask Chloe Lattanzi, daughter of “Grease” star Olivia Newton-John, who hit up Share Nightclub in Sin City with her mom on Saturday to attend the 35th anniversary celebration of “Xanadu” and the premiere of the mother-daughter duo’s new music video for their song, “You Have to Believe.” The song is a remix of Newton-John’s 1980 tune, “Magic,” released off the “Xanadu” soundtrack.

The 29-year-old aspiring singer-songwriter looked Vegas-ready in a tiny white skirt paired with a gold-and-white bralette top, while her 66-year-old mother also sparkled for the occasion — albeit more casually in jeans, a white T-shirt and a jacket with silver stripes.
