Ariana Grande has led tributes to the victims of the London terror attacks
Seven people were killed and nearly 50 injured after three terrorists reportedly drove a van into pedestrians before stabbing victims in the vicinity of London Bridge and Borough Market.
Ariana, 23, who is holding a benefit gig in Manchester tonight after 22 people were killed in a suicide bombing at her concert there last month, took to Twitter to share her tribute to the victims of last night's attack, saying simply: "Praying for London."
Many other stars followed suit, with model Cara Delevigne, 24, taking to Instagram, saying: "My heart is with you London. Please can everyone stay safe. This is beyond tragic but we must stand together and not let this break us."
Bette Midler, 71, added: "More sorrow and grief at the hands of madmen in London. Men and religion are worthless."
