Erin, on the other hand, looked a lot happier as she walked beside her beau carrying more bags and also smoking.
The brunette made the most of the sunny weather by wearing a multi-coloured floral maxi dress and tan pumps as well as a black rucksack.
The paper also reported that Daniel had a brief fling with his “Kill Your Darlings” co-star Erin Darke, 28, but that has reportedly since ended.
The “Harry Potter” star has also been previously linked to Laura O’Toole, who he co-starred with in “Equus” on Broadway, and Olive Uniacke, the stepdaughter of a one of the “Potter” producers.
Daniel and Erin didn't care who was watching as they carried shopping bags through Manhattan's West Village whilst holding hands.
When contacted about the breakup, Rosie's father responded: groupies on occasion… Perhaps Daniel dipped his quill in another lady's inkwell while he was with Rosie?!?!
Well, we're hoping that's not the case, but if it is, couldn't Daniel have simply performed a memory charm on his ex-ladylove?!
Radcliffe and Darke have done a good job keeping their relationship under wraps.
My first reaction, of course, is heartbreak, because I still believe that I am the chosen one for The Chosen One, but it seems like Radcliffe is over the moon for the 29-year old actress and casting assistant, so I begrudgingly wish him well.
