The exact timeline of Austin Butler and Vanessa Hudgens’ breakup is unknown, but the former couple did not celebrate the festive season together in 2019, according to Us Weekly. News of their split broke in January 2020, coinciding with Butler’s newfound closeness to his “Elvis” co-star, Olivia DeJonge, prompting cheating rumors. MTV reported sightings of Butler and DeJonge, who plays Priscilla Presley in the biopic, being very tactile with each other as early as December 2019. However, it is unclear whether Butler was unfaithful, as the exes might have already been separated at the time. 

Butler and DeJonge went on to have a rumored fling during the filming of “Elvis,” but nothing serious came of it. Despite this, many fans remain unconvinced. Several took to Reddit to discuss Butler’s infidelity, not sparing any feelings. One person wrote, “[He] literally threw away his ten-year relationship by cheating [with] someone else.” Another user suggested that Butler simply didn’t want to get more serious with Hudgens, asserting, “He never wanted to marry [Hudgens], so ‘Elvis’ was his getaway car.”

Nevertheless, according to a People source, Butler and Hudgens simply didn’t work out. The insider explained that their “busy work schedules and travel definitely put a strain on the relationship.” Despite all the online drama, the cheating rumors have never been confirmed, leaving it unclear whether infidelity played a role in Butler and Hudgens’ breakup.
