"About last night... @RobertsEmma @becbecbobec love them!" she wrote, adding wine and heart emojis.

She also showed off her enviable abs while doing a yoga pose.

"Sunday sweat in hot yoga," Michele wrote.

The multi-talented star has made no secret that she's been working hard on her fitness as of late, displaying her slim physique by posting multiple pics of herself at SoulCycle this month. 

The last time the singer mentioned Paetz on social media was on Feb. 8, when she posted a black and white photo of the two watching The Bachelor.

People was first to report Michele and Paetz's breakup.

Michele and Paetz met in April 2014 while filming her music video for "On My Way." The model was her first boyfriend since the death of her Glee co-star and longtime love, Cory Monteith, in July 2013.

Last month, Michele gushed about her then-beau when she spoke with Fempire podcast hosts Becca Tobin, Keltie Knight and Jac Vanek. Michele said Monteith would have definitely approved of Paetz.

"At the end of the day, this industry is really tough, and the only way to get through is to create a solid unit, and that’s really what we’ve been since day one," Michele said. "We've stood by each other through anything that was thrown our way. [Matt] is a such a great man that he would never really let anything like that ever crack our lovely little core that we've created."

"He is very respectful towards the person that I was with, and that, again, is something I love so much about him," Michele continued, adding, "I really know that Cory would love him too."
