She has also won three graded stakes in the United States and Canada, and finished second to American Horse of the Year California Chrome in the 2014 Hollywood Derby.

[1] Her dam is Oneexcessivenite, a California bred mare who won 4 times in 18 starts, and whose three previous foals were all unraced.

[3] Lexie Lou was sold to John Ross for $5,577 at the 2012 Canadian Thoroughbred Horse Society yearling sale.

She made a strong move going three wide around the far turn, but could not quite catch the front-runners and finished third by just over half a length.

[8] On June 15, Lexie Lou stamped herself as one of the best three-year-old fillies in Canada by winning the Woodbine Oaks by 4+1⁄2 lengths.

For the Queen's Plate on July 6, Lexie Lou was the lone filly in a field of 15 and was made the 3-1 second choice by the bettors.

Exiting the final turn, she had several lengths to make up on the leader but responded to urging from Husbands to win commandingly.

[7] In the Canadian Stakes on September 14, Lexie Lou faced older fillies and mares for the first time.

[11] On October 25, Lexie Lou traveled to Santa Anita Park for her first start outside Canada in the Grade III Autumn Miss Stakes.

Her connections felt that she would be helped by the firmer turf in California compared to the conditions at Woodbine in the Canadian Stakes.

Now ridden by Corey Nakatani, she made a powerful run down the stretch to win by 1+1⁄4 lengths in a good time of 1:33.70 for one mile.

[12] On November 29, Lexie Lou stepped up in class by entering the Grade I Hollywood Derby at Del Mar.

[14] On January 17, Lexie Lou debuted as a four-year-old in the La Canada Stakes at Santa Anita Park as the even money favorite.

She broke well but reacted poorly when another horse sprinted in front of her for the early lead, causing dirt to be kicked in her face.

[15] After competing in nine stakes races in nine months, Lexie Lou was given some time off, then resumed training for an August return to the track.

[16] Lexie Lou finally returned to the racetrack on January 13 in an Allowance Optional Claiming race at Tampa Bay, finishing third.

On May 29, Lexie Lou returned to form in the Grade II Nassau Stakes at one mile on the turf.

[18] On July 3, Lexie Lou entered the Grade II Dance Smartly Stakes at Woodbine as the second betting choice.
