Alexandria Forrester was the daughter of Thorne Forrester and Darla Einstein. Through a misunderstanding between Thorne and his ex-wife Macy Alexander regarding Macy's estranged husband, Lorenzo Barelli, Thorne got drunk and slept with Macy's best friend, Darla, though he thought he was making love to Macy. The encounter ruined Darla's friendship with Macy, and Darla wanted an abortion, but Thorne talked Darla out of it. When Macy died later that year, Darla named her daughter Alexandria in honor of Macy. Thorne and Darla got married and happily raised Alexandria.
Alexandria was devastated when Darla died falling into the path of an oncoming car while helping Phoebe Forrester change a flat tire on a foggy highway. Alexandria received comfort from Phoebe's psychiatrist mother, Taylor Hayes. Later, little Alexandria was the catalyst in healing the decades-old rift between her grandmother, Stephanie Forrester, and her great-grandmother, Ann Douglas.
Eventually, Thorne and Taylor became a couple and planned a wedding. During Alexandria's play date with Hope Logan, Hope innocently blabbed that Taylor drove the car that killed Darla. (The inebriated Taylor had gotten behind the wheel to help Phoebe, hitting Darla due to the fog and Taylor's impaired response time.) Alexandria ran away, and a sober Taylor went after her, almost running Alexandria down on the same foggy highway. Little Alexandria couldn't understand how Thorne could marry Taylor and blacked pictures of Taylor out with a crayon. After Alexandria shredded Taylor's wedding dress, Thorne and Taylor called off their wedding. Thorne continued raising Alexandria as a single parent, with Alexandria only seen on holidays and special occasions.
In 2013, Alexandria resurfaced as Aly, a college student who came home needing to complete an independent survey; Thorne and Aly's grandfather, Eric Forrester, put Aly to work at Forrester Creations. The earthy Aly enjoyed a close relationship with her father and spoke of the recent encouragement she had received from Sally Spectra, longtime friend to her deceased mother, Darla. Aly was instructed to "shadow" her childhood friend, Hope, who had become very successful at Forrester. After Aly developed a crush on Hope's on-again-off-again boyfriend, Liam Spencer, Quinn Fuller, who wanted Hope to be with her son, Wyatt Fuller, gave the unassuming Aly a makeover and sent her on a mission to distract Liam.
Aly visited Thorne when he took a position running Forrester International in Paris, becoming unreasonably hostile toward Wyatt; Aly felt Wyatt distracted Hope from the purity message she layered into her Hope For the Future (HFTF) clothing line. Aly, who had been bullied in school, built a shrine to Hope and had visions of Darla; it was revealed that "Darla" had told Aly to shred Taylor's wedding dress years before.
Aly slapped Wyatt when she caught him in bed with Hope. Later, Aly learned that Wyatt had pocketed a rare diamond so he could impress Hope by recovering it; Aly wanted to tell Eric, but was stopped by Quinn, who held Aly over a second-story railing to intimidate her. Aly ratted Wyatt out anyway, but was furious when Eric chose not to prosecute in order to avoid a scandal.
Aly bonded with Forrester photographer Oliver Jones, confessing that she hated Taylor for killing her mother. When Thorne brought Taylor home to tell Aly they were once again engaged, Aly threatened Taylor with an axe. Oliver convinced Aly to hear Taylor out; after Taylor admitted how guilty she still felt for robbing Aly of her mother, Aly relented and gave Taylor and Thorne her blessing. Aly continued to see Oliver, even taking him to a medieval-themed outing with her great-aunt Pam Douglas and Pam's boyfriend, Charlie Webber.
Aly ran away when Oliver revealed that a recording had been made of him saying he was only dating her because she was a Forrester. While at Medieval Times with Pam and Charlie, Aly saw that Oliver had replaced one of the "knights" on horseback to prove his devotion to her. Aly forgave Oliver and later worked on a medieval story with him, Pam, and Charlie.
Aly became best friends with her cousin Ivy Forrester, who had come to Los Angeles from Australia. Later, Taylor visited, offering to be a mother to Aly after hearing that Aly was still having visions of Darla. Aly assured Taylor she was fine and watched as Darla's ghost physically fluttered Taylor's hair.
Aly felt targeted when her half-uncle Rick Forrester took over as CEO of Forrester Creations; Aly suffered Rick's taunts, which included Aly agreeing to wait on Rick and massage the feet of Rick's mistress, Maya Avant, after Rick hinted he'd develop Aly's fledgling shoe designs. When Aly's other-half uncle, Ridge Forrester, commandeered control of Forrester from the tyrannical Rick, Aly's relief was short-lived -- Aly felt Ridge's daughter, Steffy Forrester, flaunted her sexuality modeling lingerie and trying to seduce Liam away from Ivy.
Aly loudly opposed Ridge's California Freedom line and accused Oliver of ogling Steffy during a photo shoot. Aly's saintly visions of Darla turned dark; believing she was carrying out Darla's orders, Aly pretended to go along with Ridge's collection, which was to showcase transgender models, including Maya; it was also revealed that Aly had only pretended to forgive Taylor. Continuing her descent, Aly created a hate board with blacked-out photos of Maya and Steffy. Aly punctured Steffy's tire and tried to run Steffy down in the exact spot where Darla had died years ago. Refusing Steffy's conciliatory overture, Aly came at Steffy with a tire iron, which fell to the ground; when Aly moved to bash Steffy's head in with a rock, Steffy grabbed the tire iron and swung at Aly, who fell, hit her head, and died.
Weeks later, Ivy had a dream about Aly, in which Aly demanded justice for her death.
