Billie Eilish got cozy with influencers Odessa A'zion and Quenlin Blackwell over the weekend, sparking speculation among fans that they may be in a throuple relationship.

Eilish was captured on video kissing and canoodling with Blackwell and A'zion at Coachella in Indio, California.

In one video posted by a fan on TikTok and shared by TMZ, the "Bad Guy" hitmaker and Blackwell can be seen standing among a crowd of festivalgoers when Eilish approached the 23-year-old influencer.

Eilish -- who was last romantically linked to Jesse Rutherford -- cradled Blackwell's face with one hand and gently pulled her down to kiss her on the lips.

The smooch was quick, with the pop star immediately turning away after the show of affection.

But the flirting didn't stop there as Eilish was also filmed grinding with and smacking Blackwell's behind as they danced on stage, as seen in a video shared by TMZ.

In another footage from Coachella, Eilish and A'zion can be seen embracing and sticking close to each other while dancing.

At one point, Eilish held the "Grand Army" actress by her waist and neck as A'zion moved her face close to the singer's neck.

A fourth video showed the three dancing and swaying together with Eilish in the middle.

Eilish, Blackwell and A'zion's flirty displays had fans speculating about their relationship.

"I think Odessa, Quen, and Billie are dating," one TikTok user speculated.

Another comment read, "I'm thinking either throuple or 3 girls close friends with benefits."

A third fan gushed, "They're so perfect together."

The videos also sparked a discussion over at Reddit.

"They [seem] to be in some type of [throuple]," one Reddit user suggested.

Another claimed, "Let's face it, they're all f**king each other. Good fun."

"The way this kiss is done and how she turns away is giving some fanfic realness right here," another fan wrote of Eilish and Blackwell's sweet kiss.

However, some pointed out that the kisses and hugs may be a sign they're in a romantic relationship.

"She kisses all her friends from what I've seen," one TikTok user said of Eilish. "I'm not surprised."

Eilish, Blackwell and A'zion have been pals for some time, with the singer and actress popping up on Blackwell's TikTok videos.

The videos came as Eilish debuted a new song about being in love with a woman during a surprise appearance at Coachella Friday.

"I could eat that girl for lunch / Yeah, she dances on my tongue / Tastes like she might be the one / And I can never get enough," she sings in the track, according to lyrics posted by a fan account on X.

Eilish confirmed last year that she came out as queer in her interview for Variety's Power of Women issue, in which she opened up about being attracted to women.

"I have deep connections with women in my life, the friends in my life, the family in my life," the singer told the magazine. "I'm physically attracted to them. But I'm also so intimidated by them and their beauty and their presence."
