Translation anyone?
Is it really about her new boyfriend?

I had a little time again so I checked this out.
ok here goes:
Yaguchi Mari might fail again in her private life
For ex Morning Musume Yaguchi Mari (23) a new situation arose. Photos of Yaguchi being with someone were published in a weekly newspapers.
In a magazine paparazzi photos were published that were taken of Yaguchi with actor Oguri Shun (23) which made her say "I failed as an idol" and resulted in her retirement from Momusu. After that she began pursuing a solo career but in June the relationship with Oguri has obviously come to an end. After that in just 3 months a new love was revealed.
Yaguchi's new love interest is a good-looking man who seems to be working in a bar. On a late night in the second half of this month in Tokyo they were seen on a date in a bar called Sangenja. They were heard calling each other as "Mari" and "Teru-kun" in a very intimate manner. Taking a short glimpse of Yaguchi and the black shirts, black pants wearing Teru-kun, they looked like a couple.
At the cashier's Teru-kun only wanted to chip in with 500 yen, but then Yaguchi generously payed the whole amount.
"With the tall Shun the 37cm difference in height was always an issue. But Teru-kun is around 160cm. With the 145cm tall Yaguchi they look like an ideal couple. It's just that the way he got out of paying is a little alarming." a reporter said.
Before her relationship with Oguri rumour said that Yaguchi was linked to Johnys Jr. member and to Oshio Manabu. This relationship might be even stranger compared to those past ones.
Let's hope that she can be as succesful in her private life as she is in her career.
