New Idea is excited by a small bump below the Duchess of Cambridge's belt, while Woman's Day tells of the special lingerie Jennifer Aniston bought for a dream trip to Paris with lover Justin Theroux.

In contrast, the Woman's Weekly has its eyes focused firmly onshore as it celebrates its 80th birthday issue, with former Prime Minister Helen Clark topping a list of women who have shaped this country.

But back to Kate M Middleton. New Idea reports that her "rounded stomach" is sparking a "big baby buzz". The magazine has a picture with the evidence.

Onlookers were apparently "stopped in their tracks" in upmarket Chelsea recently, with all eyes drawn to the way Kate's chic belted black dress emphasised a "small but delightful belly bump".

Other hints include blotches and spots on her skin, on which there was no make-up, along with regrowth of her hair in its natural colour.

Woman's Day is more interested in plans the Duchess is thought to be putting together for husband Prince William's 30th birthday.

It said Kate had reportedly been having "secret" meetings with the prince's friends, and that she plans to surprise him with a portrait of herself by English artist Nicky Phillips.

For Woman's Day Jennifer Aniston is the main event this week.

With just 48 hours' notice that Justin Theroux was taking her to Paris, she spent thousands of dollars on a trip to her favourite designer lingerie store, the magazine reported.

The money went on  a "collection of sexy underwear - push-up bras, thongs and garters - fit to thrill Justin Theroux in the world's most romantic city".

New Idea also had a Jen story, but it was more of an add-on to they royal pregnancy story, asking: "Is Jen Expecting?"

The suggestion arose because Aniston attended a Hollywood gala in a gown that had "conspicuous sex appeal", but drew attention away from loose fabric gathering at her waist and a "very un-Jen bulge around her belly".

The magazine also reported on Myley Cyrus being seen "cavorting" in a hotel pool in Miami with her assistant and long-time friend Cheyne Thomas. She indulged in the behaviour despite being recently engaged to Liam Hemsworth.

It has a picture of Kirstie Alley looking tubby, and said the actress reportedly weighs 91kg, and is eating comfort foods because of a flailing career and non-existent love life.

But things are going well for Los Angeles-based Kiwi-Australian actor Charles Mesure, who has landed a role on Desperate Housewives, although he would still like to settle down in this country.

Both magazines have double page spreads on The GC, with Woman's Day reporting on the romance between stars Jade Louise Dewson and Tame Noema.

The pair have had to refrain from public affection for weeks as the TV3 show played out their now committed relationship.

"We literally met, had a conversation, and the next morning woke up beside each other," Dewson said.

Noema - who moved in with Dewson and her son Harlem, nine, virtually straight away - is looking forward to: "Wedding bells. Children. The rest of our lives together."

In New Idea, show star Nathan Waikato talks about his girlfriend Brookie James, who is from New Zealand. The have been dating for eight months.

James auditioned for The GC, but was unsuccessful, even though her first cousin is actress Keisha Castle-Hughes.

Woman's Weekly is altogether more sober as it marks eight decades of publication after being launched in the depths of the Great Depression.

Its list of the top 10 women who have shaped New Zealand, actually has 11 names as the Topp Twins share eighth place.

After former PM Clark in the top spot, comes suffragist Kate Sheppard, aviatrix Jean Batten is third, followed by writer Janet Frame, former Governor-General Dame Silvia Cartwright, Dame Whina Cooper, politician Marilyn Waring, The Topp Twins, businesswoman and philanthropist Dame Rosanne Meo, and netballer Dame Lois Muir.
