This one's no mystery — Gillian Anderson's daughter is drop-dead gorgeous!

The X-Files alum, 46, attended the Olivier Awards 2015 on Sunday, April 12, in London, and brought her 20-year-old daughter Piper Maru Klotz along as her date. The gorgeous duo were a vision on the red carpet in matching black strapless gowns. 

Anderson was glowing as she stood beside her daughter with her hair pulled back in loose curls. The actress, who was nominated for her role as Blanche DuBois in a West End production of A Streetcar Named Desire, accessorized with elaborate chandelier earrings, a dazzling diamond bracelet, and a black clutch. Klotz (whose father is Anderson's first husband, Clyde Klotz) matched her mom's elegance in black midi dress, which she paired with a thin necklace and strappy sandals.

Though Klotz has inherited her mother's looks, does this mean she also picked up the acting bug, too? Not so, The Falls actress revealed to Stylist magazine in 2013 (via Telegraph). "She just did her first play and hated it," she said. "I'm relieved; it's not an easy road to choose." 

Earlier this month, Anderson's former X-Files costar David Duchovny confirmed to Us Weekly that there is indeed a reboot of the beloved sci-fi series in the works. "I don't know if it's easy yet until I do it," he told reporters on Thursday, April 2, in Pasedena, Calif., at a promotion junket for his new show Aquarius. "I've always wanted to — we always wanted to keep it going," he said.
