Power couple Justin Timberlake and Jessica Biel grabbed eyeballs as they dressed in their scariest costumes at the annual star-studded Casamigos Tequila Halloween Party in Beverly Hills on Friday.

The 37-year-old model dressed up as her husband, sporting a curly wig to channel his iconic "NSYNC" look, while her 38-year-old husband went as her microphone. Two more guests joined them as other members of the boy band, reported E-News website.
