Britney Spears quotes ex Justin Timberlake in latest Instagram

Britney Spears has not been holding back on Instagram recently, including a reference to her ex-boyfriend Justin Timberlake.

Britney Spears’ recent Instagram spree featured a photo of a large grey cat and used a lyric from ex Justin Timberlake’s song “Filthy” in the caption.

“As JT would say ... haters gonna say it’s fake !!!!! I MEAN ... wow I have no idea ... what do you guys think…????” Spears wrote.

Fans apparently interpreted the caption as a hint that a collaboration between Spears and Timberlake might be in the works. “Ok I’m off JT’s wagon, but if you guys collabed, I would hop back on so fast,” wrote one person.

The pop singers famously dated from 1999 to 2002 but never released any music together. Timberlake and Spears did perform together at the Super Bowl halftime show back in 2001.

Timberlake, 40, recently spoke out in support of Spears during her ongoing conservatorship battle.

“After what we saw today, we should all be supporting Britney at this time. Regardless of our past, good and bad, and no matter how long ago it was… what’s happening to her is just not right,” he began. “No woman should ever be restricted from making decisions about her own body.”

The star continued: “No one should EVER be held against their will… or ever have to ask permission to access everything they’ve worked so hard for.”

In February, Timberlake also apologised to Spears and Janet Jackson amid the fallout he received following the release of the Framing Britney Spears documentary. The program led fans of Spears to speak out against Timberlake and Diane Sawyer for the way they treated the pop star in the past.
