Berlin, Germany - Not long after Heidi Klum offered insights into her love life with husband Tom, she was seen shopping at a Berlin sex shop. Now, fans are starting to get a better idea of what's going on in Heidi Klum's sex life.

As German network RTL reported, the 47-year-old model was spotted on a sexually-inclined shopping trip with her mother Gerda and her brother-in-law Bill. The three went into a luxury sex shop in Berlin.

The store has no shortage of enticing products, either: In addition to a large selection of toys, the store also contains fetish accessories such as whips and gags.

The catwalk beauty is said to have had a particularly long look around the costume department. Is she perhaps planning to surprise her husband Tom with a hot new outfit?

Heidi also seemed to have found something, as she was seen leaving the store carrying a bag. What items she bought will have to forever remain an enticing mystery, though.

What is certainly clear, though, is that Heidi Klum and Tom Kaulitz's sex life is no longer a secret, and is certainly saucy.

Having bragged about the size of his wand at a party earlier this year, we already know that Heidi Klum's husband Tom Kaulitz is well-endowed.

In addition, the America's Got Talent judge has been quite open on her Instagram page over the past few weeks, even offering us a glimpse into a romantic evening in the bathtub.

The American citizen, who owns a huge villa in Los Angeles, is currently staying in the German capital.

Over the next four months, she'll be in front of the camera for the new season of her show, Germany's Next Top Model.

Heidi is rumored to be staying at the Soho House Berlin hotel with her children Leni (16), Henry (14), Johan (13), and Lou (11), as well as Tom.

So there will be plenty of time for more spicy shopping trips in the heart of Berlin!
