The couple are busy promoting the last installment of "Twilight" franchise "Breaking Dawn 2" and were accompanied by co-star Taylor Lautner, reports thesun.co.uk.
However, Stewart said she missed her co-stars in recent past and did not like giving interviews without them.
"For the last few press junkets, they've been separating everyone which is silly. I think because we love hanging out," she said.
Pattinson had broken up with Stewart in July bringing their three years of relation after the latter was caught having an intimate affair with director Rupert Sanders.
However, the couple reconciled after the actress' repeated attempts winning back Pattinson.
