London, Mar 31 : English actress Sienna Miller has been turning her thumbs sore with the text messages she has been sending to boyfriend Rhys Ifans, who is 5,000 miles away from her.
Sienna, who is currently shooting her new GI Joe movie in LA, is missing the 39-year-old Rhys so badly that she has been sending him lovey-dovey text messages every few minutes, making it about 53 text messages in just eight hours.
"Sienna is missing Rhys massively and they have stayed in constant contact," the Mirror quoted a friend, as saying.
"She boasted that they sent each other 53 texts in the space of eight hours.
"We've also been telling her that if she doesn't calm down she'll end up with repetitive strain injury - and won't ever be able to text him again!" added her pal.
The 26-year-old actress took the advice and began using her other hand to ease the burden.
"Sienna's started trying to use alternate hands to give her thumbs a bit of a break," the friend said.
