ET has learned that Britney Spears is 'very happy' after reuniting with her 17-year-old son, Jayden Federline, in Los Angeles. Britney shares Jayden James and 18-year-old son Sean Preston with her ex, Kevin Federline. The reunion comes months after Mark Vincent Kaplan, an attorney for Kevin, told ET the boys had a 'desire' to speak with their mom and have had 'some telephonic communication.' It also comes after an old interview with the pop star went viral online. In the clip, Britney makes rare comments about her 13-year conservatorship while speaking on ‘The Jonathan Ross Show’ in 2016.
