But it seems the actress is now confident enough in her new relationship to go public.
Glowing with happiness, a stunning Jennifer walked the red carpet last night, hand in hand with Alex.
He seemed equally smitten, gazing down adoringly at his admittedly beautiful companion.
Jennifer split from her Ghost Whisperer co-star Jamie Kennedy in March after a year-long relationship.
It was first reported in July that the actress, 31 had started a new relationship with actor/ director Alex, 27.
The two were spotted together on a couple of occasions, although they never commented on their relationship.
Even earlier yesterday they laughingly attempted to pretend they weren't together as they spotted a paparazzi.
The couple were obviously saving their grand unveiling for the charity event Rock the Kasbah, presented by Richard Branson and Eve Branson at The Dorothy Chandler Pavilion in Los Angeles.
