Perhaps it's their ability to uncover the truth about evil goings-on. Perhaps it's their brilliant research skills. More likely, it's a desire to do an exposé on them, finding out just what is under that lovely blouse.
Journalists who are attractive, basically.
A popular character in action movies and cop shows, as it's a good way to introduce a love interest who has a plausible reason for following the hero into danger. Sometimes overlaps with Action Girl, though it predates the latter trope's popularity by a good many decades, as it was more acceptable for a woman to be a nosy Boswell than a butt-kicking Battle Babe.
Common characteristics of attractive female journalists are an abundance of "moxy", with "gams-a-plenty" or "legs from here to Kalamazoo".
Can overlap with School Newspaper Newshound if it's set in a school. See also Intrepid Reporter and Going for the Big Scoop... which is not about dating the reporter, but their tendency to seek out danger.
While generally good(ish), a minority of these characters turn out to be true villains. Generally this sort overlaps with The Vamp.
Title is Just for Pun- a three way one on exclusive, catch and scoop-neck top.
Akari Tsukumo, older sister to protagonist Yuma Tsukumo in Yu Gi Oh Zexal, is a journalist. With just one good look at her in the manga, and this trope definitely applies.
Lois Lane from Superman, who may be one of the earliest examples of the trope.
Betty Brant from Spider-Man. Also Norah Winters, who is very, very aware that she falls into this category.
Vicky Vale, especially in the 1989 Batman movie, where she is the main female lead and is played by none other than Kim Basinger. The Joker becomes obsessed with her.
Sundra Peale from Nexus. It turned out that she was actually a spy, and working as a reporter was just her cover identity. Nipsy Conniption is a more amoral example of this type.
Filthy assistants on Transmetropolitan are reporters in training. Nothing about Yelena, but Shannon certainly qualifies because she is, well, a former stripper.
Film
Katie Holmes' character in Thank You For Smoking used her attractiveness to get an exclusive interview with Nick Naylor.
The Vanity Fair reporter in Iron Man. This is the only reason Tony Stark talks to her in the first place.
Reporter: Do you ever lose an hour's sleep? Stark: I could lose a few with you. [Cut To Sex]
In the action movie Metro (1997) Eddie Murphy's cop character is dating a black British photojournalist, Veronica "Ronnie" Tate.
Asakawa Reiko in the Japanese horror film Ringu and Rachel Keller in the American remake, The Ring.
Martha Hackett (played by Marisa Tomei) in The Paper. When she phones her editor/husband with an actual hot scoop, he asks her "What are you wearing?"
In an instance of Adaptational Attractiveness, Daily Prophet gossip reporter Rita Skeeter in the Harry Potter films looks better than described in the books, due to being played by Miranda Richardson.
Roxanne Ritchi of Megamind, a deconstructive parody of Lois Lane.
Kimberly Wells in The China Syndrome. Deconstructed in a way, as her sexist boss relegates her to fluff pieces due to her attractiveness, never giving her the much-desired chance to cover serious news.
Lexie in Leatherheads, who almost immediately becomes the object of a love triangle with Dodge and Carter.
The Discworld's Sacharissa Cripslock grows out of her prim-and-properness into one of these... although she's actually only moderately attractive, but is stunningly beautiful when considered over several centuries.
According to the interviews, Ginny Weasley ultimately grows into this in Harry Potter. More exactly, she becomes a professional quidditch player, and then a quidditch reporter after retirement.
Jackie from Life on Mars and Ashes to Ashes. Bonus points for being Scottish and all the UST with the show's chiefCowboy Cop, Gene Hunt. Between the series, they even had a one-night stand...or so Jackie pretends when she's pregnant, for the lulz.
Kate Lockwell in Star Craft II, later promoted to lead anchor. Apparently the Crown Prince has a crush on her.
Rebecca Chang from Dead Rising 2. Most of her introductory cutscenes consist of her waving her butt and tits in the hero's face while going on about Going for the Big Scoop. This may or may not have multiple meanings.
Madison Paige from Heavy Rain Her scenes mostly consist of fan-disservice, like when she's nearly raped at gunpoint.
Real Life
Nellie Bly◊, real name Elizabeth Jane Cochran. While in her twenties she was a reporter for Joseph Pulitzer's New York World who did stories exposing the horrible conditions in an asylum by pretending to be an insane patient. For her newspaper she emulated Jules Verne's Around The World in 80 Days, doing it in just 72.
BBC economics editor StephanieFlanders is quite the Christmas Cake. Of course, it helps that she's a member of a famous family of entertainers noted for their good looks (she accounts Olivia "Thirteen" Wilde as a half-cousin).
She's also the daughter of Michael Flanders; the looks are from her mother's side.
And then of course there's Fanservice first, news second Naked News, "the program with nothing to hide". Its attractive female anchors perform stripteases as they present the news, and often tape segments at nude beaches and resorts, and even on the streets interviewing pedestrians, since it is legal to be topless in Canada.
