Taylor Swift is searching for the perfect London property to be a base for her while she is in Europe.
However, if the 23-year-old singer was to buy in the area she was seen looking in, it would mean that her ex-boyfriend, One Direction's Harry Styles, would be just around the corner.
Taylor was seen eyeing up potential pads in the north west London region - just a short walk away from Harry's north London home - along with her entourage on Friday.
A source told the Sunday People: "Taylor loves London and wants to live here for extended amounts of time so she's looking for a place. She saw three properties in north west London.
"But if Taylor was to buy one of the apartments, she would almost certainly bump into Harry regularly. It's surprising that Taylor has done this.
"Those around her would have thought she'd do anything to avoid looking like she could be moving in on Harry again."
Taylor and Harry enjoyed a 65-day romance last year before they called it a day after a row during their holiday in the Caribbean.
Since then, they have kept their distance, but Taylor hit headlines at the MTV VMA awards in August when she made a backhanded comment about Harry while picking up her video award for I Knew You Were Trouble.
Collecting the prize, Taylor said: "I also want to thank the person who inspired this song, who knows exactly who he is, because now I got one of these!"
But in an interview on The Jonathan Ross Show to be aired next week, Harry insisted that he is 'still friends' with Taylor.
When Jonathan asked him about how he prevents feuds between his exes, following both Taylor and Cara taking part in the recent Victoria's Secret lingerie show, Harry said he does his best to stay pals with his former girlfriends.
Kind-hearted Harry and the rest of his One Direction band mates have just launched a special celebrity telethon via Twitter while a host of other stars will answer calls from people donating to the Disasters Emergency Committee's (DEC) emergency fund.
The charity has so far raised £35 million for the humanitarian effort in the Philippines.
