The cute couple, who played man and wife in the 2005 film and team up again as lovers in new movie Love & Other Drugs, often text each other cooking queries.
Hathaway has been taking cookery lessons to perfect her kitchen skills and Gyllenhaal is considered one of the best celebrity chefs in Hollywood – so they always have a lot to text about.
The actress tells Entertainment Weekly magazine, “I now have a go-to cooking teacher, which is wonderful.”
Gyllenhaal adds, “She texts me when she has questions about cooking… The other night, Annie texted me and she was like, ‘How can I make breadcrumbs quickly?’
“I wrote all these instructions, and it took me 15 or 20 minutes. And she goes, ‘Oh, yeah, I already thought of that. That doesn’t work.'”
