Prince Charles and Kylie Minogue share a giggle at his gala

Prince Charles is no stranger to celebrities, but he was definitely charmed by golden girl Kylie Minogue at his Prince's Trust Invest in Futures gala dinner on Thursday (Jan. 4). Looking gorgeous in a gown embellished with gold and sequins, the 47-year-old singer arrived with her boyfriend, Joshua Sasse, before sharing a giggle and a chat with her host on the red carpet.

Kylie has met the prince on a number of occasions – Charles presented Kylie with her OBE in 2008 – and he looked delighted to see her again. The pair laughed together as they caught up at the event, which was held at the Old Billingsgate, with Kylie proudly introducing Joshua to him.

During the star-studded gala, Kylie also took to the stage to perform for the prince and his guests, Charles was suitably impressed. "Her voice and movements get better and better every year," he remarked after watching the Australian star sing.

Among the guests at the glittering gala were Geri Halliwell and Christian Horner, Guy Ritchie and his wife, Jacqui Ainsley, and Jerry Hall. Both couples married last year, while Jerry recently got engaged to media mogul Rupert Murdoch after a whirlwind four-month courtship.

Guy Ritchie and wife Jacqui were among the guests.

Kylie may well have an announcement of her own to make soon. The star has been seen wearing an impressive diamond ring on her engagement finger in the last few weeks, and it was clearly on display on Thursday.

The ring appears to be a baguette-cut design with a blue diamond at the centre surrounded by two halos of smaller white diamonds. While Kylie hasn't confirmed her engagement to British actor Joshua, she has spoken openly about how they are the perfect match.

Kylie and Joshua Sasse started dating last September.

"I can't actually put into words how happy I am… we just completely fit together," she said of her boyfriend of five months. "He gets me, I get him."
