After "Mean Girls," Jonathan Bennett starred in "Cheaper By the Dozen 2" as Bud McNulty and also landed a two-episode appearance on "Veronica Mars." He'd go on to appear in a handful of TV movies, many of which were holiday originals on the Hallmark and Lifetime channels. In 2016, Bennet got an eight-part role on the hit MTV series "Awkward." as Ethan. The actor also made an appearance in a "Sharknado" film, playing Billy the Kid in 2018.
Bennett famously showed up in Ariana Grande's "Thank U, Next" video, where she parodied her favorite films, one of which was "Mean Girls." He also appeared on Season 2 of "Celebrity Big Brother," and lasted 10 days before being evicted. He came in 11th place, but funnily enough, he was in the house with Dina Lohan, his former "Mean Girls" co-star's mother. The two had an alliance, but unfortunately didn't make it until the end.
Bennett is still filming holiday and horror films and is very active on Instagram, where he often posts photos with his "Mean Girl" co-stars, like Daniel Franzese and Lacey Chabert.
