Jack Whitehall was left uncharacteristically red-faced this evening as singer Lizzo outrageously flirted with him and Harry Styles.

The BRITs presenter, 31, was clearly not ready for the American singer's quick-witted quips as he sat down to chat in between performances.

As he asked her about performing at Glastonbury, she failed to answer and said that she had got "lost in his eyes".

A flustered Jack tried to change the subject by addressing her "very racy performance" with Harry Styles.

She went on to tap Harry's shoulder as he sat behind her and he turned around and she clasped his hand.

"Back off," Jack joked to Harry and admitted that he was "a little jealous" watching them together on stage.

"I thought if you wanted an Englishman you might want someone a little more mature, a little posher," he said.

As he wrapped up his chat with Lizzo and thanked her for speaking to him, she grabbed a flute and played it.

"I feel like a snake in a basket, I've been snared," he quipped.

She grabbed Jack's head and pulled it towards her cleavage, prompting Jack to make a startled sound.

Burying his head in his notes, Jack gasped: "Oh my god!"
