Zendaya, 29, has revealed her top wedding guest etiquette rules, including wearing white to another's wedding unless they tell her otherwise. She also mentioned that wedding hashtags are "done," but won't judge a cash bar. She said that smashing wedding cake is a big no, and that wearing an Apple watch on your wedding day is a no-go. The actress-singer also highlighted the importance of good music for a successful wedding. Rumours of Zendaya's marriage have fueled speculation, with her longtime stylist claiming she secretly had a wedding with Tom Holland.
