Lovejoy began hosting and producing football show Soccer AM on Sky Television in 1996, with Helen Chamberlain. He remained on the show for eleven years.

Lovejoy married Jade in 2002 and has twin girls from the marriage, born in 2002. Lovejoy was in a relationship with English netball player Tamsin Greenway. She gave birth to the couple’s first child together, a daughter, on 22 May 2013. In May 2016, Lovejoy announced that this relationship had ended.

In 2006, Lovejoy was appointed as the co-host of the car show Fifth Gear on Five for one series.

From 2006 until 2012, Lovejoy co-presented the Sunday morning TV programme Something for the Weekend on BBC2, opposite chef Simon Rimmer and various female co-hosts including Louise Redknapp (previous co-hosts include Amanda Hamilton and Caroline Flack).

Lovejoy announced on 5 June 2007 that he would be leaving Soccer AM after eleven years.

In 2008, Lovejoy launched an internet TV channel called Channel Bee. As of 20 November 2009, the website has been taken down.

Following his departure from Soccer AM, Lovejoy joined BBC Radio 5 Live as the Wednesday night host of its football phone-in show 6-0-6 though he was dropped in 2009. He also presented the UK edition of Five’s Major League Soccer magazine show David Beckham’s Soccer USA

In 2009, Lovejoy was named by The Daily Telegraph as the 49th most eligible bachelor in Britain.

In February 2010, Lovejoy guest presented an episode of Blue Peter 12 years after auditioning for the show. A clip of Lovejoy’s original audition was shown during the programme.

In 2010, Lovejoy made a cameo appearance as a news reporter in the comedy feature Being Sold.

Lovejoy participated in the 2011 series of Celebrity MasterChef.

It was reported in January 2012 that the show, which in 2011 ran as a 46 × 90-minute series, had fallen foul of the BBC’s Delivering Quality First cuts because of its unfortunate scheduling on BBC 2 during the day, despite consistently high ratings. The show ended in March, and an online campaign was launched to save the programme.

On 25 March 2012, Lovejoy and Rimmer began hosting a new show for Channel 4, Sunday Brunch. The series started one week after the final episode of Something for the Weekend.

In August 2013, Lovejoy began hosting the Saturday morning BT Sports Panel (BTSP) show of predictions, previews and reviews – a format similar to his former Soccer AM days.

In 2014, Lovejoy and Rimmer presented a short-lived spin-off series called Daily Brunch, airing Monday to Fridays from 10 am. The show lasted for just eight weeks.

In 2017 Lovejoy launched Dear Lovejoy, originally an agony uncle podcast, but later evolving into a series of interviews.
