Housewife kids Sophia Umansky, Nick Dubrow and Mason Grammer "will be on Next Gen LA," Us Weekly can exclusively confirm - and filming is underway. Kyle Richards and Mauricio Umansky's daughter Sophia, 26, was recently spotted at Galerie nightclub in Los Angeles "with the whole crew filming for the sizzle reel," a source tells Us, adding that filming is "early in the process" for the new Bravo series, which has yet to be officially announced by the network. Us Weekly has reached out to Bravo for comment.
