Gwyneth Paltrow and Chris Martin were determined to get a picture with PSY at the Met Ball.

The 'Iron Man 3' actress and her Coldplay singer husband were surprisingly starstruck when they spotted the 'Gangnam Style' hitmaker at the Costume Institute Gala in New York City on Monday (06.05.13), and asked him for a snap so they could show their children, Apple, eight, and seven-year-old Moses.

Madonna will be honoured with the 'Top Touring Artist' award at the 2013 Billboard Music Awards.

The 'All of the Lights' rapper - who was accompanied to the star-studded annual Costume Institute Gala in New York City on Monday (06.05.13) by his pregnant fiancée Kid Kardashian - was one of the musical stars who took the stage at the event, but left organisers and guests scratching their heads by playing several unfamiliar tracks from his new album.

Madonna reportedly ''summoned'' her daughter Lourdes' boyfriend for a meeting.

The singer's 16-year-old daughter has begun a romance with 'Homeland' star Timothee Chalamet - a fellow pupil at LaGuardia drama school in New York - and after the 'Hung Up' hitmaker discovered the news she wanted to meet him immediately.
