March 9 (UPI) -- Rob Kardashian posted new photos of Dream on Wednesday amid rumors of an imminent custody battle.
The 29-year-old reality star called the 3-month-old his "motivation" and "inspiration" following reports he and ex-fiancé Blac Chyna are gearing up for an "ugly" fight for custody.
"Dreeeeezy," he captioned a photo of the infant on Instagram before adding, "This is my motivation. This is my inspiration."
Kardashian and Blac Chyna welcomed Dream in November after getting engaged in April. The couple reportedly called it quits again in February following a highly-publicized breakup in December.
"[It's the same] with her yelling and screaming about how his family doesn't like or support her, and his insecurities," a source told Us Weekly.
People reported Wednesday that Kardashian's family has rallied around him in the wake of the split. The star is the son of late attorney Robert Kardashian and Kris Jenner, and the brother of Kourtney, Kim and Khloe Kardashian.
"I expect things to get ugly," a source told the magazine. "Chyna wants full custody with Rob only getting visitations."
"[His family members have] always had their issues with Chyna but they were happy when the relationship was working and when Rob was happy," the insider added. "But at the end of the day, they all raise an eyebrow at Chyna and her intentions."
Kardashian has shared a slew of new photos with Dream in the past couple weeks, including a picture of the infant smiling. Sister Kim Kardashian also posted a first-ever photo of herself with Dream on Tuesday.
