A backstage interview with Lady Gaga is causing a stir online after the star flashed a little more skin than expected.

The megastar's right breast was blurred out through much of an hour-long interview on CTV's eTalk, which premiered Saturday night and was to air twice Sunday afternoon.

Posts on Twitter jokingly referred to the apparent exposure of a nipple as a "nip-slip."

But host Ben Mulroney said he barely noticed the slip-up and that the blurring was just a precaution.

Asked on Twitter whether the so-called "nip slip" was awkward, he replied: "Really, it wasn't so bad. we're just being careful. :)"

He later tweeted: "To be honest, I didn't even notice the 'nip slip"'.

Gaga wore a black halter bra, fishnet tights, over-the-knee boots and fingerless gloves.

It wasn't her only wardrobe malfunction that night -- many reported a similar blooper during her performance in a skit with Justin Timberlake on Saturday Night Live.

The singer, who is one of the most followed people on Twitter, made no mention of either incident on the social networking site.
