Miranda Lambert Covered No Doubt's 'Spiderwebs' Just One Month Before Divorcing Blake Shelton

The 'Crazy Ex-Girlfriend' singer covered a song by ... the 'Ex-Girlfriend' singer who is now dating her ex-husband. Mind. Blown.

We bet Miranda Lambert wishes she could take some kerosene to this performance.

The “Bathroom Sink” singer performed a cover of No Doubt's "Spiderwebs" -- one of the SoCal band's biggest singles from their breakout 1995 album, Tragic Kingdom -- during an appearance at Joe's Bar in Chicago on June 6.

You read that right: the "Crazy Ex-Girlfriend" singer covered a song by the woman who penned "Ex-Girlfriend" and is dating her ex-husband, Blake Shelton.

Lambert didn't put a country spin on the ska-pop track when she sang it on stage over the summer. Instead, she kept true to the tune, rocking out to the track by Gwen Stefani's group in what basically felt like live-band karaoke.

Between the white tank top and black fishnets, even Lambert's outfit was very Stefani-esque. But the most eerie part of all is the timing -- the performance came just six weeks before Lambert announced her divorce from Shelton, who is now dating Stefani, a fellow judge on The Voice.

The coincidences only get weirder. Lambert was performing with Permnent Damage, a group comprised of her touring band and crew members.

She jumped on stage to sing a couple of songs alongside singer Gwen Sebastian -- a season two competitor on The Voice who had been on Team Blake and later toured with Lambert and Shelton -- for covers of "Spiderwebs" and B-52's "Love Shack."

That is a whole lot of Lambert/Shelton/Stefani overlap all in one night. Plus, let's not forget that just two nights ago, Lambert rocked pink dip-dye hair at the Country Music Awards, and it was pretty impossible to not compare the look to the Stefani of old, who had a very similar 'do for years.

Still with us? Good. You can watch Lambert's whole cover below. Not only does she look very happy while singing with Sebastian, she also sounds great.

Lambert can clearly be seen flipping through lyrics at the beginning of the performance, so while she may have dug the song -- and, at 31, she is the perfect age to have been influenced by Tragic Kingdom during her middle school years -- the Texas native is clearly no Stefani diehard.

We also doubt she's a big fan of the hollaback girl now, though we do hope she can at least find some solace in shouting this line back at Stefani:

Like Lambert, Stefani also went through a split this year. The 46-year-old singer filed for divorce from her husband of 13 years, Bush frontman Gavin Rossdale, in August. The divorce was settled in October, with the two agreeing upon joint custody of their three kids, 9-year-old Kingston, 7-year-old Zuma and 1-year-old Apollo.

Rumors began flying last month that following his split from Lambert, Shelton, 39, had started dating Stefani. Following photos surfacing from the Halloween weekend the two co-workers spent partying together, Stefani's rep confirmed the relationship. The acknowledgement took place just hours before Shelton and Lambert attended the CMAs, which marked the first time the exes were both at a high-profile function since their divorce.

Watch the video below to see how Lambert reflected on her "amazing life" after learning of Stefani and Shelton's coupling.
