Baby photos next for Terry

CONTROVERSIAL photographer Terry Richardson is moving into a new chapter at 50 — fatherhood.

Multiple sources tell Page Six that Richardson’s former assistantturnedgirlfriend Alexandra Bolotow is pregnant and that the couple’s been discreetly telling friends.

A source further told us that Bolotow’s three or four months along.

We’re told 30something Bolotow has known Richardson for 10 years, and she appeared in 90 explicit photos by the fashion photographer in his 2005 book, “Kibosh.” She reportedly met him when she was still an NYU student, then became an intern for Rich ardson before working for him full time and later studying anthropology at Columbia.

Bolotow was also one person who rushed to Richardson’s defense last year during a media firestorm when he was accused of sexual misconduct by a number of models, though none of them ever brought charges against him.

“I think part of being a strong woman is owning the decisions that you’ve made in your life,” Bolotow said in a 2014 New York magazine cover story on Richardson and the controversy. “Trying to put the onus onto someone else for your own decisions is really cowardly and kind of dishonest.”

Richardson — who’s known for shooting subjects from Barack Obama and LeBron James to Miley Cyrus, Lady Gaga and Beyoncé for magazines like Harper’s Bazaar and GQ — had penned his own piece refuting the claims, saying, “I have never used an offer of work or a threat of rebuke to coerce someone into something that they did not want to do. I give everyone that I work with enough respect to view them as having ownership of their free will and making their decisions accordingly.”

In New York mag, Bolotow said that she and Richardson “have a lot of conversations about things — the weird moral quandary of sexual things.” Seems the conversations will soon extend to diapers. Bolotow, Richardson and his rep didn’t get back to us.
