"Fifty Shades Freed" is looking to be hot. The final installment in the "Fifty Shades" series has added another addition to its roster by casting Arielle Kebbel. The "Ballers" actress will be cast as the seductive Gia Matteo.

In a report with The Hollywood Reporter, Matteo will come to challenge Anastasia Steele and Christian Grey's relationship as Anastasia becomes jealous of the sexy architect as Christian Grey calls Matteo a "sexual predator." The alluring architect is tasked to design Christian Grey and Anastasia Steele's mansion.

Dakota Johnson and Jamie Dornan are set to reprise their roles as lovers. They have now matured in the relationship and have decided to settle down. But what happens when the lovers of the past come back to haunt Ana?

In the sequel, Ana and Christian are moving forward with their relationship, having been married and planned a future together. The last installment in the series will follow Ana and Christian's life as a married couple and Ana dealing with her pregnancy. She finds that she also has to deal with the pains of the past as Christian's past lovers come back to haunt the couple.

According to the website, "Fifty Shades Darker" will be filmed alongside "Fifty Shades Freed." Bella Heatcote has been cast to play Leila, who becomes an emotional wreck after being seduced by the cold and calculating Christian Grey. Kim Basinger has also been cast to play another one of Grey's former lovers, and was typecast into the role of a certain "Mrs. Robinson." 

The Daily Mail reported that Kebbel's character will act as a thorn in Ana's side as she finds that she has to deal with the architect's seductive and flirty ways which she finds less than welcome around Christian. Unfortunately, the beautiful architect turns out to be good at her job and Ana has a hard time finding ground in that.

"Fifty Shades Freed" is expected to be out in theaters in February 2018. The script is being written by Niall Leonard, E.L. James' husband and the inspiration behind Christian Grey.

The script is said to be risque, but Leonard has promised to keep the naughty bits of the film to a "tasteful minimum."
