A Rockefeller allegedly romanced a potential business colleague, then tossed her aside and ruined her rep, she claims in a lawsuit.

Christopher Rockefeller Lindstrom, 38, whose grandfather David Rockefeller was worth $3.3 billion when he died in 2017, began courting Jennifer Collins last summer, asking her to dinner, promising to introduce her to business contacts and offering to paint her portrait after he spotted a nude image of her on her cellphone, she claims in court papers.

The two slept together twice even though Lindstrom was dating another woman prominent in a Washington D.C.-based nonprofit called Nexus, Collins claims in her Manhattan Federal Court filing.

Lindstrom had promised to be a reference for Collins, who wanted in on Nexus’ 2018 youth summit, but they broke up before she applied, she charges.

The self-described “social entrepreneur” and entertainer claims Lindstrom then blackballed her and got her barred from the summit, to which she had been given a scholarship to cover the $1,250 cost.

“He told a third party they shouldn’t work with me,” the 30-year-old claimed.

Nexus, which connects the wealthy with socially progressive entrepreneurs, didn’t investigate, she charges.

“They took his word without any questions being asked, without any investigation,” she said.

A lawyer for Lindstrom said Collins filed similar legal claims earlier this year, which Lindstrom in court papers denied and called “frivolous.”

Nexus spokesman Ronn Torossian said the group “believes this is a meritless case and that the court will ultimately agree.”
