Los Angeles - Taylor Swift's stage invader has pleaded not guilty to all charges.

Christian Ewing, 26, was arrested and charged after being taken down by four of the Blank Space hitmaker's bodyguards when he snuck into her concert at Petco Park in San Diego, California on Saturday night and jumped up on stage alongside the star.

He was charged with assault with force, battery with serious injury, misdemeanour for giving a false name and a municipal code violation for getting into the concert, and his bail has been set at $100 000.

However, Ewing has denied all charges.

A source told gossip website TMZ.com that Ewing charged towards the 25-year-old beauty while she was performing Style and attempted to fight off her security in a bid to get closer to her.

Although he was eventually dragged away, one member of Taylor's team is believed to have suffered a broken rib during the incident.

District Attorney Jessica Coto said in court that when asked why he went on stage, he said, "I love that girl".

He is due back in court on 14 September.

Ewing is not the first security scare for Taylor, the Bad Blood hitmaker has been forced to secure restraining orders against a number of stalkers in the past.

Timothy Sweet, 33, was ordered to stay away from her and her parents, Andrea and Scott, for three years in March 2014 after he sent her dozens of e-mails, letters and social media posts declaring his love for her.

He also allegedly threatened to "kill any man", including US Secretary of State John Kerry, who came between him and Taylor, as he believed he and the singer were married.
