The Kilkenny native -- who is enjoying parenthood with her partner Brian Fitzsimons -- said her bouncing baby boy is entirely doted on.
"He's probably the most adored child I can think of! He has loads of love and support and it's been great for us, what with him being our first baby," she told the latest issue of VIP magazine.
According to Evanne, Brian, a youth worker, is the world's best dad.
"Brian has taken to fatherhood like a duck to water. Seimi is just mad about him. We love being parents and it's a happy time, albeit a stressful one."
While some well-known faces claim to see their baby weight disappear without much effort, Evanne is far more honest and admitted that she initially found it difficult to shift the baby bulge.
"I put on quite a bit of weight but I started going to the gym when Seimi was two months old," she revealed.
"I couldn't do anything before that because I had a C-section and recovery was slow. In the last few weeks, I've kicked it up a gear and have tried to pay more attention to nutrition."
The sports presenter has been on a familiar fixture on RTE for nearly 10 years and Evanne says she's happy to be back at work.
"It's been a good experience. When you're at home with a baby, you tend to concentrate on them and their routine, but I think both both Seimi and I have enjoyed a bit of independence since my return to work."
Evanne has also opened up about her struggle with postnatal depression.
When she returned home with baby Seimi, Evanne said she turned into an emotional wreck.
"I was just crying, sobbing at the drop of a hat,' she said.
"If someone had said to me that I would be crying the week after I brought my new bundle of joy home, I wouldn't have believed them."
Evanne said she was so stressed out that she was constantly picking fights with Brian.
"I was arguing with himself. One day I completely lost it about how much broccoli he was putting on for dinner. They were ridiculous things but I didn't seem to be able to help myself. I seemed powerless to stop it.
"I remember crying for a couple of days but if you asked me now I wouldn't be able to tell you why. I cried when the big man was at work and when the little man was asleep in my arms."
Evanne said that while she didn't endure the depths of post natal depression some mothers go through, she did battle with the baby blues.
"It wasn't until after that I realised lots of women go through this.
"It's all normal. It's okay to say you're feeling depressed or sad or overwhelmed. It shouldn't be taboo but it still is."
