For a couple who officially broke up, Jennifer Lawrence and Chris Martin are still seeing a lot of each other.

On Oct. 27 – the same day that sources confirmed the split – the Mockingjayactress visited Martin’s Malibu home for several hours. But that wasn’t the last time she was spotted visiting his place: She returned three nights later, on Thursday.

The pair went out separately Friday, with Lawrence, 24, “having a great time” atJustin Timberlake and Jessica Biel’s Halloween party, while Martin, 37, went trick-or-treating in Malibu with ex Gwyneth Paltrow and their kids Apple, 10, and Moses, 8.

On Saturday, Lawrence was spotted driving to Martin’s Malibu house again.

While one source tells PEOPLE that the pair have indeed split, another insider says they remain an item.

“They’re very much together,” the insider tells PEOPLE. “He’s very much into her and they’re still seeing each other.”

A rep for Lawrence has not commented.

As for other sources’ contention that Lawrence is bothered by Martin’songoing closeness to Paltrow, “she doesn’t give a s— about Gwyneth [and Chris’s relationship],” says the insider, adding that the Hunger Games star thinks the reports are “hilarious.”

Lawrence recently bought Jessica Simpson’s former Beverly Hills house for $8.2 million but has yet to move in. Since their romance began this summer, she has often gone the extra mile to meet Martin on his turf.

“In the beginning, they would spend almost equal time in the Beverly Hills-West Hollywood area and Malibu,” another source says. “Lately, they have mostly been spending time at his Malibu house, which means she has to drive back and forth” – about a 90-minute commute.

But she’s about to get very busy: The Hunger Games: Mockingjay – Part 1kicks off a promotional blitz with a world premiere in London on Nov. 10.

Paltrow, meanwhile, recently heaped praise on her ex, calling him “father of the year” at a gala for the AIDS charity amfAR on Thursday
