Samuels made her first appearance for WWE on Raw and SmackDown in 2014 as a Rosebud, accompanying Adam Rose to the ring.
Samuels competed in her first match on the NXT brand in 2018 in a six-woman tag team match where Candice LeRae, Dakota Kai and Tegan Nox defeated Samuels, Bianca Belair and Lacey Evans.
On August 25, 2018, Samuels competed in the NXT UK Women's Championship tournament first round where she was defeated by Dakota Kai. On January 23, 2019, Samuels faced Lana Austin, where Samuels was victorious. Samuels faced Toni Storm for the NXT UK Women's Championship on April 19, 2019.

On October 8, 2020, Samuels teamed with Amale, where they were defeated by Xia Brookside and Dani Luna. Samuels walked out on Amale halfway through, offended that Amale was stealing her spotlight. That same night, Samuels later appeared with the rest of the NXT UK roster to confront Kay Lee Ray. On October 22, 2020, Samuels and Amale went one-on-one, where Samuels was victorious. On November 12, 2020, Samuels went up against Xia Brookside. In the match, Samuels attempted to fake a knee injury but it backfired when Brookside rolled her up for the quick win. After the match, however, Samuels still gained the upper hand by assaulting Brookside at ringside. The feud between Samuels and Brookside would continue week after week. Notably, Samuels cost Brookside a match against Isla Dawn on December 10, 2020. Eventually, the two faced off again on the February 4, 2021 episode of NXT UK, where Samuels was victorious after hitting Brookside with her handbag. Brookside demanded a rematch where the loser became the winner's personal assistant for a whole month. On February 25, Brookside defeated Samuels in that match. Throughout March, Samuels would be forced to work as Brookside's assistant much to her chagrin.
On the July 1 edition of NXT UK, Samuels made her return to television in the hope of being the first to challenge Meiko Satomura. However, her return was interrupted by Amale, who viciously attacked her. Samuels made her in-ring return on the July 22 episode of NXT UK, with an enhanced entrance and a new finishing move. As a result, she successfully defeated Laura Di Matteo. However, on August 12, Samuels was defeated by Amale. On August 26, Samuels attempted to be granted a rematch against Amale, but instead she was given a match against Blair Davenport for the following week. However, the match never began as Davenport attacked both Samuels and assistant to the general manager Sid Scala before the bell. Following this, Samuels began her own show called The Nina Samuels Show, where she would begin interviewing various superstars of NXT UK. On the November 18 episode of NXT UK, Samuels was defeated by Aleah James.
On August 18, 2022, Samuels was released from her contract.
