Nicole and Brianna Garcia were born sixteen minutes apart on November 21, 1983, in Brawley, California and raised on a farm in the outskirts of Scottsdale, Arizona.

[4] A year later, the twins relocated to Los Angeles in pursuit of acting and modeling opportunities, making ends meet doing various gigs from marketing for a now defunct record label, to cocktail waitressing at the Mondrian Hotel.

[7] On September 14, the twins made their in-ring debut defeating Nattie Neidhart and Krissy Vaine with Victoria Crawford as the special guest referee.

[13] In FCW, the twins competed in bikini contests and wrestled against Katie Lea Burchill, Milena Roucka, and Nattie Neidhart.

[24][25] In February 2009, the storyline expanded to include John Morrison and The Miz, who flirted with the Bellas and took them on a date for Valentine's Day.

[26][27] The date provoked a rivalry between the teams of The Miz and Morrison and Primo and Carlito, with the four competing for the affection of the twins, who were seemingly unable to choose between them.

[28][29] On March 17 on ECW, Carlito and Primo, aiming for Morrison and The Miz, accidentally spat apples in the face of Brie.

[36] They quickly developed a storyline feud with Katie Lea Burchill, when Nikki defeated her in a match by switching places with Brie behind the referee's back.

[43] The next week on Superstars, the twins defeated Hall and Maryse in a tag team match to end the storyline.

[59] On a special "Power to the People" episode of Raw on June 20, Brie defended her WWE Divas Championship against Kelly (who was selected by voters), losing the title and ending her reign at 70 days.

[61] The Bellas began to show friction in March 2012 after both twins lost to AJ Lee in singles competition.

[75][76] The twins made their in-ring return defeating The Funkadactyls on the March 27 episode of Main Event after interference from Cody Rhodes.

[83] At Night of Champions on September 15, Brie unsuccessfully challenged Lee for the Divas Championship in a four-way match, which also involved Natalya and Naomi.

[97] The next several weeks saw the twins fight in several backstage and in-ring segments, including a cameo appearance from Jerry Springer on Raw on September 8.

[99][100] At Hell in a Cell, Nikki defeated Brie in a match where the loser was forced to become the winner's personal assistant for 30 days.

[102] Nikki retained her championship in three separate occasions—against Lee in a rematch at TLC: Tables, Ladders & Chairs on December 14,[103] against Naomi two days later on SmackDown[104] and against Paige on February 22, 2015, at Fastlane.

[110] At Elimination Chamber on May 31, Nikki retained her title against Naomi and Paige in a triple threat match, with Brie banned from ringside.

[115] After weeks of Team Bella outnumbering Paige, Naomi and Tamina, Stephanie McMahon called for a "revolution" in the WWE Divas division and introduced the debuting Charlotte and Becky Lynch as Paige's allies while NXT Women's Champion Sasha Banks debuted as an ally to Naomi and Tamina, which led to a brawl between the three teams.

[120] On the September 14 episode of Raw, Nikki defended her title against Charlotte, who pinned Brie after the twins had switched places to win the match, but she retained the championship since the title cannot change hands by disqualification and in the process became the new longest reigning Divas Champion in history, surpassing AJ Lee's previous record of 295 days.

[121] On September 20, Nikki dropped the championship to Charlotte at Night of Champions, ending her reign at 301 days[122] and failing to regain the title in a rematch at Hell in a Cell on October 25.

[123] Shortly after, Nikki went on a hiatus from both television and in-ring competition due to a neck injury which would require surgery,[124][125] but returned for one night on December 21 to accept the Slammy Award for Diva of the Year.

[133] On April 6, Brie confirmed that she would be taking an extended break from in-ring competition, citing family reasons while also stating that she will continue working for WWE as an ambassador.

[134] On January 22, 2018, on the Raw 25 Years special episode, The Bella Twins were honored as part of a segment involving women considered legends that contributed to the company's success.

[136] On the September 3 episode of Raw, The Bella Twins competed for the first time in three years, defeating The Riott Squad (Liv Morgan and Sarah Logan).

The Bellas teamed with Ronda Rousey to defeat The Riott Squad at WWE Super Show-Down on October 6 and won the rematch two nights later on Raw.

[139] At February 21, 2020 edition of SmackDown, it was announced that both Bellas will be inducted into the WWE Hall of Fame, during A Moment of Bliss segment.

[4][148] Nikki and Brie are part of the main cast for the reality television show Total Divas, which began airing in July 2013.

[151] Nikki and Brie co-starred in the 2014 independent film Confessions of a Womanizer and provided voices for the 2015 movie The Flintstones & WWE: Stone Age SmackDown!.

[162] On April 16, 2020, the twins were featured on the hit YouTube channel "First We Feast", appearing a Truth or Dab edition of Hot Ones.

[163] On August 21, 2017, Nikki and Brie launched their own wine label called Belle Radici in collaboration with Hill Family Estates and Gauge Branding.
