Jessica Biel finally reacted to the surprising Instagram exchange of former lovers Britney Spears and Justin Timberlake. Everything started when the '90s pop princess danced to the music of her ex-boyfriend's hit song, "Filthy," to which JT left a comment on.

The 38-year-old singer-songwriter showed some of her signature moves, not to mention her sexy figure, on Instagram. She put a lengthy caption on her clip, mentioning the former NSYNC member's name and remembering their controversial breakup 20 years ago. She said it was her version of Snapchat or TikTok or whatever cool thing people find to do these days during the coronavirus outbreak, admitting she was very bored. 

"PS I know we had one of the world's biggest breakups 20 years ago ...... but hey the man is a genius !!!!" she wrote. "Great song JT!!!! Pssss if you KNOW WHAT'S GOOD!!!!!!"

Despite their lousy breakup, Justin Timberlake didn't ignore Britney Spears' video. He made it known that he approved of his ex-girlfriend's use of his song and left a crying/laughing emoji with a couple of praising hands emojis.

So, what does Jessica Biel think about it? None. According to HollywoodLife, a source revealed that the 38-year-old actress had no issue with Britney Spears and Justin Timberlake's Instagram exchange. She was even totally cool about it.

The insider added that it was even nice to see people happy about their reconnection. The Sinner star is confident that nothing romantic will come from their online interaction. She is also glad that it makes people happy in this time of crisis when they need it the most.

Britney Spears and Justin Timberlake, on the other hand, are said to be on "great terms" despite their controversial split. Sources close to the pair revealed that they already reconnected a couple of years ago and even have a "great friendship."

Justin Timberlake is, reportedly, surprised and touched that Britney Spears called him "genius." He has now moved on from everything that happened between them in the past and only wished her nothing but the best.

Britney Spears and Justin Timberlake started dating in the late '90s and parted ways in 2002. The "SexyBack" hitmaker knew that they were still young at the time, so as a lot of time had passed, it was all water under the bridge. Anyhow, he saw her post as something hilarious but found it sweet that she gave her a shout out.
