In November 2011, it was reported that Moinet had signed a contract with WWE and was assigned to their developmental territory Florida Championship Wrestling (FCW). Moinet made her televised debut on the December 18 episode of FCW TV, appearing in an in-ring promo with Abraham Washington. She also served as the ring announcer for FCW TV for several months. Changing her ring name to Summer Rae, she was prevented from interfering in a match between Seth Rollins and Rae's new client Brad Maddox by the debuting Paige on the March 5 episode of FCW TV.

Rae made her official debut on WWE's main roster on the April 22, 2013, episode of Raw, as Fandango's dance partner and valet. On the May 13 episode of Raw, Rae, along with Fandango, faced Chris Jericho and Dancing with the Stars competitor Edyta Sliwinska in a dance-off, but Fandango's dance was cut short by an apparent injury to Rae's ankle. However, Rae later revealed that her injury was a distraction to trap Jericho into Fandango's attack. On the October 25 episode of SmackDown, Rae got into a brawl with Natalya during a match between Fandango and The Great Khali, which set up a mixed tag team match for Hell in a Cell in which she made both her pay-per-view and in-ring debut on the main roster, teaming with Fandango to defeat Natalya and Khali, after Rae pinned Natalya. The following night, Rae made her singles debut in a rematch against Natalya, where she was defeated. At Survivor Series on November 23, Rae participated in a seven-on-seven elimination tag team match, as her team took on the cast of Total Divas, where she was eliminated by Nikki Bella, before her team ultimately lost the match. A rematch took place the following night on Raw, where her team was once again defeated, with Rae being the last to be eliminated. On the December 19 episode of Superstars, Rae defeated Kaitlyn, garnering her first singles match victory on the main roster. In the beginning of 2014, Rae began a rivalry with Emma, and the two competed in several dance-off and wrestling competitions on both Raw and SmackDown, which Emma won. On April 6, Rae made her WrestleMania debut, competing at WrestleMania XXX in the 14-Diva "Vickie Guerrero Invitational match" for the Divas Championship, which was won by the defending champion AJ Lee.

Rae has appeared in five WWE video games. She made her in-game debut at WWE 2K14 as a DLC and appears in WWE 2K15, WWE 2K16, WWE 2K17, and WWE 2K18. In 2014, Rae was a main cast member on Total Divas for the show's second and third seasons. Rae also starred in the 2015 film The Marine 4: Moving Target alongside The Miz.

In June, Rae became involved with Rusev's storyline with his former manager Lana and Ziggler, in which Rae formed an on-screen relationship with Rusev. After weeks of confrontation, Rusev faced Ziggler at SummerSlam, which ended in a double countout due interference from both Lana and Rae. In September, Rae attempted to sabotage Ziggler and Lana's relationship, but the storyline was abruptly dropped. After Rusev refused Rae's marriage proposal, Rusev's real-life engagement to Lana was revealed, leading to Rae confronting Rusev and ending their association on the October 12 episode of Raw. Rae gained revenge over Rusev on the following episode of SmackDown when she served as the guest Referee for his match against Ziggler; she helped Ziggler. On the October 22 episode of SmackDown, during a Miz TV segment between Rae and Ziggler, she introduced the debuting Tyler Breeze as her "new man", and subsequently began managing him. However, during the final SmackDown of 2015, Rae and Breeze announced that they amicably decided to go their separate ways.

Rae returned to in-ring action in mid-February 2016 competing in various matches, where she was on the losing side. In late March, Rae allied herself with Team B.A.D. (Naomi and Tamina), Emma and Lana, leading to a tag team match on the WrestleMania 32 pre show, which Rae's team lost. On July 19, Rae was drafted to Raw as part of the 2016 WWE draft. However, she never appeared for the brand due to injuries. After over a year of inactivity, Rae was released from her WWE contract on October 29, 2017.
