Having made her UFC debut in 2016, Irene Aldana has had her ups and downs in the promotion, as she started off her career with a loss against Leslie Smith. However, Aldana successfully made up for it with two back-to-back wins against Talita Bernado and Lucie Pudilova, respectively.

After a loss to Raquel Pennington, Aldana won her last Octagon outing against Vanessa Melo via unanimous decision in a bout that took place at Catchweight after Aldana had missed weight.
