(Cover) - EN Showbiz - Robert Pattinson can’t go an hour without talking to Kristen Stewart, a friend has claimed.

The 24-year-old actor has been dating his 20-year-old Twilight co-star for around two years. The pair confirmed their romance earlier this year, and have been inseparable ever since.

When they are forced to be apart due to their conflicting work schedules, the pair keep in touch by constantly calling and sending text messages to each other.

“All he does is talk about her and text her,” one of Robert’s friends said. “He can’t go an hour without talking to her. And last time we were together, she called him three times in four hours.”

Robert and Kristen enjoyed a romantic break in Ojai, California, late last month. The usually-private pair shocked onlookers with their public displays of affected, with one surprised witness saying Robert couldn’t keep his lips off Kristen.

“He was leaning in to her, nuzzling her like a horse,” the source said. (C) Cover Media
