Meghan Markle will give birth by Monday night to a little girl to be named Diana - at least that's what the bets placed by punters suggest.

Britain's Prince Harry and his American wife are due to welcome their first child any day now, just ahead of their first wedding anniversary on May 19.

Speculation has long been rife on the baby's gender, name and up until Wednesday - birth month.

Many people expected the baby would arrive in April so those who bet on a May birth are likely to see a return, William Hill spokesman Rupert Adams said. He added the bookmaker had yet to settle April bets on the "unlikely" chance the baby was already born in secret.

Harry and his former actress wife announced in October they were expecting their first child this spring.

Meghan told well-wishers in January she was six months pregnant, adding the couple did not know the baby's gender.

"We actually believe it's going to be this week and we make today, Wednesday 1 May, the favourite at 4/1," Sam Rosbottom, PR executive at Betfair said.

Odds for Thursday or Friday were 5/1, he added. Should the baby arrive on May 2, the young royal would share a birthday with cousin Princess Charlotte, Prince William's daughter.

William Hill has odds of 3/1 for Wednesday.

"We reckon it's imminent now...we're odds on 1 to 2 that the baby arrives by Monday night," William Hill's Adams.

Bookmakers say for weeks, odds have favoured the baby to be a girl, with the name Diana, after Harry's late mother, leading the pack with odds of 4/1 at William Hill and 3/1 at Betfair. <a href="https://www.wionews.com/videos/royal-baby-betting-odds-may-birth-on-but-keep-your-april-tickets-215089">Watch video here.&nbsp;</a>

"The big news right now is all about Allegra," Adams said of a new addition to the top list of girl's names. "Allegra was 100 to 1 just two days ago, suddenly it's in at 12/1."

That name has also proved popular at bookmakers Ladbrokes, which earlier this week had the same odds for it.

Other names include Victoria and Elizabeth, after Britain's monarch and Harry's grandmother. For a boy, Arthur has odds of 12/1 at Betfair while Charles, after Harry's father, is at 14/1.

"We've seen quite a lot of money in the past 72 hours for Mary - that's gone from 40/1 to 14/1, also looking at Grace at 7/1 and Alice at 10/1," Rosbottom said.

The Queen visits Meghan Markle at her new home ahead of baby Sussex's arrival

Duchess of Sussex Meghan Markle threw an intimate baby shower in New York for close friends and associates on Wednesday. Celebrities like Amal Clooney, Serena Williams, Abigail Spencer were spotted at the event but actress Priyanka Chopra was conspicuous of her absence.&nbsp;

One can recall that Priyanka attended Meghan's wedding to Prince Harry last year in March. The actress is known to be close to the Duchess who was formerly an actress. <a href="http://www.wionews.com/entertainment/meghan-markles-new-york-baby-shower-has-amal-clooney-serena-williams-but-where-is-priyanka-chopra-198778">On Wednesday, as Meghan threw a baby shower at a hotel in New York</a>, guests were clicked while leaving the venue post the bash. Meanwhile, Priyanka posted a sunny selfie from Beverly Hills the same day.&nbsp;

Turns out, Priyanka could not be a part of Meghan's special day as she had prior work commitments in Los Angeles. She was busy with meetings for the memoir that she is writing.&nbsp;

The baby shower was also attended by Jessica Mulroney, designer Misha Nonoo, makeup artist Daniel Martin.&nbsp;

The hotel in which Meghan hosted the shower apparently runs US$75,000 per night.&nbsp;

Meghan is expecting her first child with husband Prince Harry. The baby is due in April. This trip to the US is her first after the wedding in May 2017. She married the royal at Windsor Castle in the UK. Prince Harry is Queen Elizabeth's grandson and sixth in line to the British throne.

Meghan and Priyanka first met a TV actress' gala dinner and then stayed in touch. Terming it as 'friendship at first sight', Priyanka had stated that the two had bonded over common interest in the field of gender equality.&nbsp;
