BRIAN McFadden and fiancee Vogue Williams are only too happy to publicly tell all about their love.
But Brian's former fiancee Delta Goodrem prefers to keep things below the radar.
The Aussie songstress has been linked to TV presenter Darren McMullen -- and it appears things have been progressing between them for some time.
The pair were spotted holding hands and kissing while in the company of A-listers Nicole Kidman and her husband Keith Urban at a Lady Gaga concert.
Delta and Darren, who is originally from Scotland, met while working together on the Australian version of The Voice which Darren hosts. Delta featured on the show as a judge alongside Keith Urban, Seal and Joel Madden.
Delta and Darren had been the subject of feverish speculation over the last couple of months.
But they preferred to keep any budding relationship on the down-low.
However, fans of both are delighted since reports emerged of the pair "exchanging kisses and holding hands for all to see" at Wednesday's Gaga concert.
The pair were at the gig as part of a 45th birthday celebration for Ms Kidman.
Delta dated former Westlife singer Brian for seven years and the pair were engaged -- but never made it to the altar.
