The 25-year-old single mother reportedly returned the Bachelor star's engagement ring, according to Us Magazine.
"It's completely over now," a show insider claimed.
Another source appeared to confirm the news, stating that the pair had allegedly split over two weeks ago.
Rumours of the couple's split first surfaced in April, but the two denied the reports, declaring that they were still engaged.
Womack, Maynard and show executives from ABC are yet to comment on the renewed speculation.
The pair reportedly ended their engagement as a result of the pressures from maintaining a long-distance relationship.
"Emily is happy in Charlotte [North Carolina] and is not moving to Austin with [her 5-year-old daughter] Ricki," said the second source.
Womack became engaged to Maynard on the season finale of The Bachelor in March.
A new season of The Bachelorette premiered on Monday evening on ABC.
