Going head-to-head with his “Spider-Man: Homecoming” co-star Zendaya, Holland opened his routine with a fake-out “Singin’ in the Rain” bit before launching into Rihanna’s 2007 smash — wig, dress and tights included.

The SFPD said they detained a person, who matched the suspect’s description, a short distance from the stabbing incident. The suspect, identified as 29-year-old Sean Collins, was transported to the San Francisco County Jail, where he was booked for homicide, police said.

Tom Holland has starred in several blockbuster movies, but for many fans, his most memorable performance was when he competed against Zendaya on Lip Sync Battle in 2017.
