Nikki Lund has posed in a Halloween ʙικιɴι before the spooky day falls on Thursday.

The siren – who took in Shawn Mendes’ concert earlier this month – wore her blonde hair down as she lay by a swimming pool in Nashville, Tennessee while modeling the orange pirate-themed swimsuit.

The size 2 cover girl from California added a silver belly chain in a shoot by Saeed Chalky shared with DailyMail.com.

The singer, who is debuting her new song Love To Love You on Spotify this month, also talked to DailyMail.com about her top three tips for staying slender during the cooler months.

‘I have three rules when it comes to my lifestyle,’ the ex-girlfriend of Richie Sambora told DailyMail.com.

‘The top one is I stay away from carbs – that means I say no to pizza pasta, which is very difficult because those two items are everywhere, on almost every menu, you can’t avoid them, and who doesn’t love pizza and pasta? So it’s a challenge.’ 

If she does crave pizza she has cauliflower crust with vegetable toppings and low cheese. And if she wants pasta she uses squash noodles.

‘You get used to the subsтιтutes and start to enjoy them, to be honest.’

The Beverly Hills native, who grew up with Paris Hilton and Kim Kardashian, said her second tip is to stay away from sugary drinks.

‘That means no Coca-Cola, no Sprite, no sweetened tea, no Frappuccinos, no sugary lattes, no Apple Martinis, they are literally wiped out of my life,’ said Lund.

‘These are what I called sneaky calorie drinks because they don’t seem fattening, but let me tell you, some of them can be 600 calories each, easily. One can of Coca-Cola is about 140 calories. Have three of those a day and you are adding 420 calories to you waistline.

‘If I want something sweet to drink I have a sip or two of lemonade, but not more than that. It’s a treat like candy so I limit my intake.’

And her third tip has to do with exercise.

‘I walks for 30 minutes in the morning, 30 minutes before lunch and 30 minutes before dinner. It’s easy because I live in a beautiful suburb and I just wave to neighbors and look at the flowers on my stroll. If I do this three times a day it is an hour and a half workout that is a no brainer.

‘Some days I walk slowly, that is if I am tired. But if I have more energy I power walk.

She had put some weight on when she welcomed her son Hendrix in 2018 but didn’t get serious about getting back her pre baby body until 2022.

The music star added that she does yoga twice a day. ‘After I have had my coffee I spend an hour in my home gym doing five Sun Salutes, the warrior pose, standing tree and lunges,’ she said.

‘Then before I go to bed I spend about 20 minutes doing more Sun Salutes because it helps me sleep better.

‘After the stress of working all day and watching my son, it’s nice to have some me time where I take care of myself, it really helps lessen my anxiety and it makes me fall asleep fast.’ 

Her previous hit tracks are This Is It and U & I as Sambora often served as mentor.   The fashion designer who also worked as a clothing designer – her items will appear in Nordstrom.
