She struggled to lose 50lbs after giving birth to son Hank Jr in 2009 and Kendra Wilkinson has admitted she is worried about weight gain with her second pregnancy. 

The 28-year-old reality TV star and husband Hank Baskett, 31, will welcome a baby girl in May but Kendra has already started piling on the pounds and is anxious about ballooning up.

'This pregnancy is extremely difficult already,' Kendra told In Touch Weekly. I'm already showing at three months and I'm gaining a lot of weight faster so I'm having to take control.'

The worried star added: 'I'm already getting these thick love handles I never got the first time around so I’m doing what it takes – I’m more active.'

It took Kendra three years to finally be happy with her body after giving birth in 2009 and she explained, 'It was three years of pure war with myself.'

Kendra surprisingly revealed that their daughter will be their last child as she and Hank are already looking to the future, without children.

'I'm done,’ she said. 'We don't want to take care of kids the rest of our lives  - we want to take care of ourselves, too. When the kids grown up, we're getting an RV. We're hippies like that.'

However, despite her pregnancy fears, Kendra couldn't be happier as Hank has been spoiling her rotten.

'He's so romantic,' she gushed. 'I get the most love and attention when I'm pregnant. Every day I wake up to roses next to my pillow or on the toiled because he knows everywhere I’m going. Being pregnant, you pee a lot.'

Earlier this month, Kendra confirmed to OK USA that the couple are expecting a girl.

'We wanted to know the sex instantly. With a new DNA blood test we didn't even have to wait for an ultrasound,' she said. 'We are people that don't like to be surprised or thrown off. We want to be in control this time.'

Just last month, the former Playboy pin-up told the magazine her son was raring to go after being an only child for so long.

Then and now: Kendra showed off a tiny waist in 2006 and hopes she won't balloon up now that she is pregnant with her second child

'He's beyond excited. He's beyond,' she said. 'I mean, it's because of him we're having another one. It's perfect timing for everyone.'

However, having been dead-set convinced that his mom was expecting a boy, the anxious parents weren't sure how he would take a news that the baby is a girl.

When we actually broke the news to him that we were having a girl, he got really excited, yelling, "I'm having a sister!"'

But perhaps it was 'Big' Hank that Kendra should have been more worried about.

'Big Hank is terrified about having a girl. His eyes were filled with fear [when I told him]. He didn't know what was going on. His whole life just flipped upside down,' Kendra laughed.
