Talk about tit for tat. Just days after ink-bedecked David Beckham shelled out a small mountain of moolah to treat mammose missus Victoria to a surprise birthday shopping spree in Paris, she returned the favor on Wednesday with an equally ritzy round of retail therapy to ring in his 32nd.

According to the Daily Mirror, the former Posh Spice lived up to her moniker by flying her soccer star hubby from Madrid to London on a private jet ($32,000) and helping him pick out plenty of pricey presents during a jaunt to swanky Savile Row.

His purchases reportedly included a watch ($28,000); suit ($9,000); some shirts ($800); and custom-made shoes ($3,800), which also happened to be one of the luxury items he bought Victoria on her birthday.

The highlight-happy, acquisitive honeys, who recently plunked down $22 million for a Beverly Hills pad around the corner from pals Tom Cruise and Katie Holmes, capped off the day with dinner and an impromptu Spice Girls reunion.

David and Victoria broke bread at tony London eatery Cipriani with several of their pals, including Victoria's erstwhile bandmates Emma "Baby Spice" Bunton, Geri "Ginger Spice" Halliwell and Melanie "Scary Spice" Brown. No word on why Melanie "Sporty Spice" Chisholm was a no-show.

Says an insider of Beckham's big day, "He was really touched that she spent so much time arranging everything and he loved every minute."

Meanwhile, speaking of TomKat, the Beckhams continue to shoot down reports that they're curious to find out what's lurking in L. Ron Hubbard's cupboard.

Victoria, whom Us Weekly recently labeled Katie's "link to the outside world," is "agreeing to study more about Scientology," a Posh "friend" alleges to the London Daily Mail, "but at the moment David is less sure."

According to the mole, Cruise "has basically been on to them both for a while now to show their commitment. The way Tom sees it is that he has shown them a great deal of commitment during their move to L.A. Tom has made it clear their continued friendship depends on a commitment to Scientology."

Not so, says the Beckham's rep, who vehemently denies that Tom and Katie have attempted to convert their new neighbors to a Thetan-free way of life.

"They are not signing up," the spokesman maintains to the paper, "and neither do they intend to do so."

A Beckham source concurs, telling People the rumors are "rubbish," adding, "Ages and ages ago Tom gave them a booklet, but that was it. There hasn't been anything more than that. It is never discussed."
