THEY APPEARED TO be love’s young dream – cheeky golden-haired crooner Bryan McFadden and his shy Australian popstrel Delta Goodrem.

Against all odds, they got together in the wake of Bryan’s split from his Atomic Kitten wife Kerry Katona, and were seen performing together on many occasions.

But sadly their unbreakable four-year union has ended – and in a rather public display of affection, Brian took to Twitter to say exactly what he thought of his former love.

They pair, who got engaged in 2007, released a statement to Australia's Herald Sun, saying:

Delta Goodrem and Brian McFadden regretfully announce that they are no longer engaged, and after much consideration, have mutually decided to end their relationship.

This decision has been made with a lot of soul searching from both parties with the realisation that they have grown apart. They leave the partnership with respect for one and other, wishing each other success and happiness for the future.

Delta and Brian.... request that their time together is respected and they are given privacy during this time of transition.

Of late, the couple had been conducting a long-distance relationship.

Just last month, Brian had written a heartfelt tweet proclaiming Delta to be the queen of his heart:

Ouch.

But Brian wasn't the first celeb to publicly gush about his love before a surprise split - and he won't be the last.

Here are some more celebs that did the same. Whoops!
