Fischer has not yet responded to a request for comment.
He's quit his long-standing TV show Saturday Kitchen, after a long 10-year stint, guest presented This Morning, he's rumoured to be next in line to present Top Gear, and now – according to sources – he's apparently back on the dating scene.
For I learn the handsome Saturday Kitchen host, who only last year seemed happily entwined with Dubai-based interior designer Julia Dempster, is now stepping out with shapely TV producer Louise Davies.
He told chums he wanted to avoid being Lord Spring because it sounds too much like a brand for bottled water.
Yet cynics suggest it has more to do with disassociating himself from the three-in-a-bed romp which brought about his resignation in 1995 as parliamentary private secretary to the then Ulster Secretary, Sir Patrick Mayhew.
More recently, he’s been working as a chef on the Vineyard, both at the Beach Plum Inn, where he served the Obamas, and, more recently, at The Covington Restaurant.
Fischer, who met Gyllenhaal at summer camp, spent many of his early years living on Jacqueline Kennedy Onassis’s Vineyard estate, where his father was a caretaker.
