R&B singer Robin Thicke‘s determination to win back his estranged Hollywood wife Paula Patton may be severed after being spotted with multiple women this week.

According to reports, Thicke recently dropped nearly $3,000 on Halloween outfits for four women at a costume shop.

Thicke hit up Trashy Lingerie — a supplier of celebrity undies — and we’re told he dropped $2,800 on his harem of hotties … buying them skimpy greek bras and skirts for Halloween. As you may recall … Thicke went on a campaign to woo Paula Patton back into his life after they broke up — but she filed for divorce anyway. (TMZ)

Despite his public pleas, Thicke recently said he had not seen Paula since earlier this year.

“I haven’t seen her for four months. She’s the best girl in the world, a great mother and still a good friend. But I also want to wish her well and let her know that she’s a great person and she deserves to have a good life,” Thicke said in an interview. “I’m a man. I messed up and I had to lie for a while, and then I stopped lying. This whole album is me revealing everything.” (Hot 97)

Robin reached out to Paula during his performance of “Forever Love” at the 2014 BET Awards show last summer.

“I’d like to dedicate this song to my wife. And say ‘I miss you’ and ‘I’m sorry,” Robin Thicke said, before performing his new song “Forever Love,” for the first time on live television. “Forever Love” follows up “Get Her Back,” both off his album dedicated and titled after his estranged wife, actress Paula Patton. “He singing like she don’t know him,” Chris Rock joked after Thicke’s performance.
