Lady Gaga seemingly called out by Dan Horton's ex wife: 'Poker Face'

Love triangle?

Lady Gaga made headlines on Tuesday after she was spotted kissing her audio engineer, Dan Horton, while on a Sunday brunch date in Studio City, California.

Horton's ex-wife Autumn Guzzardi took to Instagram to share a striking headshot with the caption "Poker Face." Commenters pointed out that she was seemingly calling out the 33-year-old singer using the title of her 2009 Grammy-winning record. One person wrote "It's good you have a sense of humor!" while another realized "She's following Gaga, she's obviously a fan."

According to Tennessee court documents obtained by ET, Horton and Guzzardi finalized their divorce in May 2018 after tying the knot in 2013, citing "irreconcilable differences."

Guzzardi's Instagram bio says that she is an actress and FLYBarre instructor. According to her IMDB page,Guzzardi has appeared in "Law & Order: Special Victims Unit" and the CBS show "Elementary."

Aside from Gaga, Horton also works as an audio engineer for other top names in the music industry including Ariana Grande, Justin Timberlake, Jay-Z, Camila Cabello and Bruno Mars.

Back in 2017, Guzzardi shared an Instagram from the Bruno Mars concert gushing over Horton.

"That time your Dream Of a Hubby got sold out Bruno Mars tickets for you and two of your friends you jumped, screamed, and danced like a little girl!
