It turns out not everyone thinks Brooklyn Beckham‘s engagement to Nicola Peltz, 25, is a good idea! The 21-year-old’s ex-girlfriend Lexy Panterra, 30, admitted she thinks he’s “too immature” to get married when she gave a tell-all interview about their past relationship to The Sun. The brunette beauty, who dated Brooklyn for a year in 2017, also said she dumped him because she was tired of his failure to take their romance seriously.
