Sonia Kruger laughs when the conversation turns to marriage. The rumour mill went into overdrive at Christmas when word leaked out that she was headed to Las Vegas with the love of her life – Today Tonight executive producer Craig McPherson – to tie the knot in the city of sin.

Photographers staked out the Elvis Wedding Chapel and reporters were winging their way to Vegas to witness Sonia’s “secret” wedding – the only problem was, the “bride and groom” knew nothing about it. But speculation about their relationship is nothing new. The pressure has been on ever since Sonia’s best mate, newsreader Chris Bath, wed sports reporter Jim Wilson and friends started asking, “When will you tie the knot with Craig?”

“I just don’t see marriage as necessary to having a great relationship,” explains Sonia, 46, who has been married twice. “It’s just not that important to me. That said, we are very much in love and plan to spend the rest of our lives together.” Equally, Sonia doesn’t rule out motherhood, although she realises her biological clock will not allow her to keep her hopes alive forever. “It was just the way my life panned out; it’s more circumstance than anything else.” Sonia says she can’t rule out children, hinting that she has explored options.

“There are ways and ways – there are a lot more options open to women now than there ever were before,” she says. “There are so many choices for women today, and I think most women can see pros and cons with all those decisions. It makes us interesting that everyone is different and makes different choices. Imagine if we were all the same!”
