Could baby number two be on the way for Liv Tyler? Rumor has it that the "Leftovers" star may be pregnant with her second child.

And she is allegedly expecting with British boyfriend Dave Gardner, best friend of David Beckham.

According to E! News, 37-year-old Tyler is reportedly covering up a pregnancy, literally. The actress has been photographed several times over the past few weeks in various baby bump-covering outfits.

On Wednesday, Tyler was snapped strolling around New York City wearing black overalls that appeared to show off her alleged baby bump.

The Daily Mail also reports that Tyler may have been keeping her pregnant tummy a secret recently. She was seen holding large hats over her supposed burgeoning bump last month during a vacation in Spain. 

"If the stork could just drop it off on my roof, I'd be so happy - I'd have, like, 20," Tyler told Seven magazine, regarding having more children.  

The actress currently has a 9-year-old son Milo William Langdon with her ex-husband Royston Langdon. Tyler and Langdon split in 2008 after five years of marriage. Gardner also has two children from a previous marriage.

According to E!, Tyler met her current boyfriend, Gardner, through mutual pal Kate Moss. Gardner, a sports agent, also happens to be a very close friend of David Beckham.

"They get on very well and are really enjoying spending time together," a source told E! News about Tyler and Gardner. "He flies to New York mostly to see her and they feel very comfortable together."

So will the couple ask the soccer superstar to be their bundle of joy's godfather? Well, Tyler has not yet confirmed that she is, in fact, pregnant. 

But the actress certainly claims to want another baby in the future.

"I hope I will have more children," she told Seven. "I'm 100 per cent planning on it."
