Britney Spears and her boyfriend dress up as superheroes
The 29-year-old singer - who is dating her former agent Jason Trawick - threw a party for her youngest son Jayden`s fifth birthday this week, and while the young guests dressed up as their favourite comic book stars, she resisted the outfits, though she admits she is happy to wear a costume in private.
Britney - who as well as Jayden also has six-year-old Sean Preston with ex-husband Kevin Federline - said: "We`ve just had a huge birthday party for him yesterday! It was Spiderman and Batman [themed], he`s obsessed, so obsessed!! We have four Spiderman costumes, so all the kids at the party had on costumes!
"Oh, I didn`t dress up at all! Nooo actually me and - I was going to say my husband - my boyfriend we do that every once in a while! We`re such Goubs! I`m so embarrassed!"
Although she enjoys dressing up with Jason, Britney insists she is actually a very boring person.
In an interview on the KISS FM breakfast show, she said: "I`m really kind of boring. I love my home and love my routine! I like my computer - we`re American so we like that!"
The `Hold It Against` hitmaker turns 30 in December and she admits she is starting to feel old.
She added: "Oh my god it`s crazy! I`m getting old!"
