The 31-year-old musician said despite hanging out with the group the day before, she was reluctant to talk to them on the sets of the romantic movie, reported Femalefirst.
"We felt like we knew Lindsay Lohan, we were hanging out, but then the next day she ignored us ... It was a cool experience playing ourselves in the movie 'Just My Luck'," Jones said.
The "Five Colours In Her Hair" singer also revealed that while the group had a great time on set for the feature, there was a lot happening in their personal lives.
