Bey loved.While his big sister’s buzzing around the globe on her Renaissance World Tour, Beyoncé’s 13-year-old half-brother — who spent his formative years living in a trailer with mom Alexsandra Wright — questions why the “Why Don’t You Love Me” singer won’t show him any affection, so claims the teen’s mother. “[He asks], ‘Why doesn’t that person love me?’,” Wright, 52, who lives in California, told The Sun of her son Nixon, who she shares with Beyoncé’s father and ex-manager Mathew Knowles, 71. “Nixon has never had the luxury of being a normal child,” Wright, an L.A.-based businesswoman, continued. “Being related to someone famous smothers kids like him and they lose their identity.”“I sit in the bathroom and cry sometimes because I just don’t know how to help him be his own person.”Representatives for Beyoncé, 41, did not immediately respond to The Post’s request for comment. Wright, a former public relations representative for Microsoft, met Knowles in Seattle, Wash., while brokering a business deal for Beyoncé in 2007. “He said, ‘I am going to stay in Seattle until you agree to have a drink with me,’” recalled Wright.
