Despite repeated denial from Team Lohan-Ronson, Star Magazine has “confirmed” British tabloid reports, which claim actress Lindsay Lohan and her alleged partner, DJ Samantha Ronson, are planning a child together.

According to the Star report, the lezzie lovebirds are diligently researching their chances of conception via invitro fertizilation-and they’ve already selected the ideal sperm donor-Sam’s own brother, record producer Mark Ronson!

“Lindsay told Sam that she’s been feeling more and more maternal in the past few months and she wants to get pregnant,” a Star Magazine insider says us. “Sam was completely overjoyed, because starting a family with Lindsay is a dream come true for her.”

“They both think that Samantha’s older brother, Mark Ronson, would be the perfect sperm donor,” their pal tells Star. “They agree that it’s the best way for Lindsay and Samantha to have a baby together.”
