Cycling articles for celebrity magazine (4)

I believe the answer is:

heat

'celebrity magazine' is the definition.
(Heat is an entertainment magazine)

I cannot understand how the remainder of the clue works.

(Other definitions for heat that I've seen before include "Raise temperature" , "Hotness" , "Warm up" , "It's measured in therms" , "Pressure" .)

I've seen this clue in The Guardian.
