Kylie Minogue and Chris Martin 'spotted taking moonlit stroll' after Hyde Park gig

Kylie Minogue, 47, was reportedly spotted taking a 'late night stroll' with musician Chris Martin, 38, following her Hyde Park gig.

According to reports, the pop princess celebrated her headline slot at the British Summertime concert by hanging out with the Coldplay frontman and wandering around central London and through St James's Park.

An onlooker told The Sun: "They were in their own little world, they seemed oblivious to anyone around them."

The pair, who have known each other for years and even collaborated in the past, were reportedly seen walking arm in arm as they walked past Buckingham Palace.

The source added: "They've been close for years and were celebrating Kylie's Hyde Park gig privately."

Martin was at the Barcalycard gig earlier in the evening where he watched the superstar from the side of the stage, clearly hanging around to congratulate her afterwards.

His former wife Gwyneth Paltrow was in the same spot just a few days previously as she watched the Strokes perform in the first of the British Summertime series.

The pair spent Father's Day together with their family, with Paltrow posting a gushing message about her husband of 10 years.

Captioning a picture of Marin with daughter Apple, she wrote: "Nothing like father/daughter love. Happy Father's Day to you, CAJM. Here is to all the engaged and present fathers, you create a backbone for society. We honor you all today."

While Martin is still thought to be dating A-lister Jennifer Lawrence, Minogue is newly single.
