A series of high-profile celebrity relationships, such as Jennifer Aniston and Brad Pitt provided ample material, while reality shows such as Big Brother and Pop Idol grew popular at just the right time to help fill pages.

Current items carrying the Heat brand name are an exercise DVD titled Heat: Get That Celeb Look which was released in 2003, an interactive DVD game featuring celebrity questions, an annual for the year 2007 and in 2003 a set of mini books titled Say What were released containing quotes from celebrities such as Gareth Gates.

In an issue which was released on 27 November 2007, Heat used a photograph of Katie Price's disabled son, who suffers from septo-optic dysplasia, a rare condition which means he is visually impaired and suffers from hormonal deficiencies, causing him to easily gain weight and means he is partially blind,[11] on a sticker which was included with the magazine, with the slogan "Harvey wants to eat me!"

[15] In another issue released on 6–12 September 2014, Heat published a photograph of Justin Timberlake, husband to Jessica Biel, at a nightclub in Paris on the night after his performance.

The singer and actor lodged a defamation claim in the courts in Ireland against the publishers of the celebrity title over an article, photographs and quotes attributed to Biel.

In the agreed statement read in the high court, a lawyer for the Heat publisher Bauer group admitted the article headlined "The flirty photos that rocked Justin and Jessica's marriage" was based on an unfounded report.

The article also included purported statements improperly attributed to Biel which the publishers said Heat now understands the actor never made.

[17] The Bauer media group later apologized on Heat magazine's behalf over these allegations, and a settlement was made in a hearing before the president of the High Court, Mr Justice Nicholas Kearns.
