Here’s how far the Cam-Rod love affair has gone — he’s going shopping for shoes with her … and they’re calling each other ‘babe!’

When a man waits patiently while his girlfriend shops for shoes, you know it’s getting serious: And that’s exactly what happened with Cameron Diaz and Alex Rodriguez yesterday. A HollywoodLife.com spy spotted the pair at the Beckley boutique in Las Vegas — and read on for all the exclusive details!

According to our source, A-Rod waited patiently while Cam shopped quickly for blush Elizabeth + James lizard evening pumps at the boutique in the new Cosmopolitan Hotel.

She asked his opinion: “Babe, what do you think?” He liked the stacked front $299 four-inch-high pumps.

But Alex gave a thumbs down to a navy shimmery Vivienne Westwood cocktail dress for $800 that a salesperson suggested. “No, babe,” was his terse judgment.

The couple — who were just vacationing with A-Rod’s two young daughters, Natasha, 6, and Ella, 2, in Cabo San Lucas, Mexico — were in a hurry to find the heels. Cam, 38, tried them on for A-Rod, 35, to check out before paying herself for the shoes.

The couple looked happy to be hanging together and were dressed casually in jeans. A-Rod wore a plaid shirt and a leather jacket and Cameron was in a sweater and jacket with red lipstick and uncombed long blonde hair.

“Are you going to the concert tonight too?” Cam asked another boutique shopper who had complimented her on her shoes, referring to the Coldplay/Jay-Z New Year’s Eve show at the Cosmopolitan. She said that she and Alex would be there.

The pair — who called each other “babe” repeatedly — seemed really comfortable and happy to be together and were exceptionally polite to everyone in the shop. “Have fun tonight!” Cameron sang out to the other shopper she’d been talking to, as she and her man headed out with her purchase.
