Los Angeles, June 4 : Actress Lili Reinhart, who is popular as Betty Cooper in the show "Riverdale", has come out as a "proud bisexual" woman. Reinhart took to Instagram Stories while promoting the West Hollywood LGBTQ+ for Black Lives Matter protest, and wrote: "Although I've never announced it publicly before, I am a proud bisexual woman. And I will be joining this protest today. Come join." The 23-year-old actress's announcement comes after reports of her split with her "Riverdale" co-star Cole Sprouse, who plays Jughead Jones in the show. Last week, according to reports, the couple called it quits on their three-year romantic bliss. However, both actors have not officially confirmed the news. Sprouse was detained for peacefully protesting in California. He took to social media on June 1 to confirm reports he was arrested by police for "standing in solidarity" with activists near Santa Monica Pier. "Riverdale" is based on the characters of Archie comics. Apart from Reinhart and Sprouse, it also features KJ Apa as Archie Andrews and Camila Mendes as Veronica Lodge. /IANS
