Rob Kardashian and Blac Chyna have been Instagramming up a storm since their most recent breakup.
While Rob is known for going silent on social media for weeks and months at a time, he's recently been doting on his and Chyna's 3-month-old daughter, Dream, by sharing lots of pics with his fans.

On Thursday night, the new dad posted three images of a smiling Dream, who's dressed in an all-pink outfit with a bib that reads: "Princess happy."
"Dreeeeezy," he captioned one of the photos. "This is my inspiration. This is my motivation."
He's not lying about the "motivation." Earlier that day, Rob also revealed that he was working out with celebrity personal trainer Gunnar Peterson at his gym.

Meanwhile, Chyna has also been working on her fitness. Since giving birth in November, the 28-year-old model has lost over 40 pounds and loves to share photos of her post-baby body. Around the same time that Rob was posting pics of Dream, Chyna put up images of herself from a recent photo shoot.
In the pics, she's seen wearing a black turtleneck crop top and matching, high-waisted bottoms that showcase her legs and stomach.

While the once-engaged couple have no problem sharing their lives with fans on social media, a source told ET earlier this week that they are no longer filming season two of their E! reality show, Rob & Chyna.
The source added that the two are, however, remaining amicable for the sake of their daughter. "They are doing the best they can to stay civil and to co-parent the best they can," the source explained. "They have worked out an informal custody arrangement. They found out what works for them and they’re doing a good job at it."
