Lady Gaga revealed her 25 lb weight gain during a radio interview this week.
And the singer kept her fuller frame covered up in a leopard-print dress while arriving at her Paris hotel on Friday night.
Lady Gaga, 26, hid her new curves under the dramatic zip-up dress with wide peplum hips, which she wore with Victorian-style black platform booties.
Mother Monster was clearly more interested in showing off her new cherub tattoo on the back of her partially shaved head – inked in honor of photographer Terry Richardson’s deceased mother – by pulling her reddish brown hair and wig into an elaborate top-knot towards her crown.
Not in France tonight was Lady Gaga’s on/off boyfriend Vampire Diaries star Taylor Kinney, who will next be seen in Kathryn Bigelow’s Zero Dark Thirty.
Earlier this week Lady Gaga told radio host Elvis Duran that she is “dieting now” after eating too much “pizza and pasta” on the road for her Born This Way tour.
“I really don’t feel bad about it, not even for a second,” Lady Gaga said.
“I have to be on such a strict diet constantly. It’s hard because it’s a quite vigorous show, so I tend to bulk up, get muscular, and I really don’t like that. So I’m trying to find a new balance.”
Lady Gaga also said she picked up her carb-loving eating habits from her dad Joe Germanotta, who owns Joanne Trattoria, a New York restaurant.
“It’s so freaking delicious, but I’m telling you I gain five pounds every time I go in there. So my dad wants me to eat at the restaurant, and I’m, like, I’ve got to go where I can drink green juice.”
But it wasn’t the star’s figure that was grabbing people’s attention as she took to the stage in Amsterdam on Tuesday night.
Lady Gaga was seen mid-show lighting a big joint of marijuana and inhaling it during a break.
Praising the “wondrous” drug, the singer told fans she had cut down on drinking alcohol because she prefers smoking the substance.
Lady Gaga was quoted as telling The Sun newspaper: “I want you to know it has totally changed my life and I’ve really cut down on drinking.
“It has been a totally spiritual experience for me with my music. It’s like saying everybody needs to take a breath and it’s going to be OK.”
Lady Gaga has been open about how hard she usually works to maintain her trim physique, and caused controversy earlier this year by revealing her diet habits.
Writing on her Twitter page, she said: “Just killed back to back spin classes. Eating a salad dreaming of a cheeseburger #PopSingersDontEat #IWasBornThisWay.”
The tweet angered many of her 29 million Twitter followers.
The five-time Grammy winner, who’s admitted to having eating disorders as a teenager, is set to make her debut film appearance in Robert Rodriguez’s upcoming movie Machete Kills.
